Blitz crashes after patching

[buttmuncher420]

There is no error message, it just closes immediately upon opening with this adblocker installed.

[MortyMcFly420]

Same here, it tries to launch but just ends poppin into close.

To elaborate more on this issue as it's crashing for many... here is an example log output from running the patcher on a fresh install of blitz. Checking for Blitz... win32 Extracting app.asar...

Opening blitz will just crash without a warning visible.

Confirmed, not working.

[MauroCastro1705]

idem

[majorcyto]

Can confirm, it is not working.

[hellabump]

same its still broken

[Sarm1X]

Can confirm its refusing to start up

[IamKevio]

I'm having the same issue. So do we know exactly why this is happening? A fix from blitz, or?? Thank you for any input.

[BroManDudeGuyPhD]

Same issue here - crashing when running Blitz

[TMKCRepo]

Can confirm. Latest release of the Adblock breaks Blitz after installed.

[Sarm1X]

Any updates regarding the issue dev? :)

[lulzsun]

I believe there is some file signature check, because any type of modification to the app.asar file will cause this crash/close on launch.

Here are the things that I have tested:

1. Extracting app.asar to /app and deleting app.asar using 7zip
2. Modify app.asar without extracting and repacking using 7zip
3. Extracting app.asar (making no changes), and repacking using 7zip

All of the above causes a crash on startup, which leads me to believe it is a signature check. I'm not sure if its an electron feature or if it is something that Blitz has done to prevent things like this, it could even be something completely unrelated to any sort of security feature as well. I haven't looked into it any deeper than the tests I have done, it is not in my priorities to dive any deeper than this.

However, there are possible ways to go around this issue. One idea that I've thought about trying is to just inject javascript into the electron renderer. Here's an example of someone doing this. If anyone wants to test out something like this, I'd like to know the results, as I am currently no longer motivated to fix this on my own time.

I have found a workaround with the following steps:

1. Install Blitz
2. Install Blit App Adblock
3. Navigate to C:\users\YourWindowsUsername\AppData\Local\blit-update *
4. Run installer.exe

Then the application seems to run ok. I am not seeing ads.

With default windows settings the AppData folder may not be visible. If you hit your windows key then type 'folder settings' and press enter -> view panel on top -> tick 'show hidden folders' option - then AppData folders will be visible.

Did the following steps, but as it seems to patch blitz right back, the application ads are still showing on my end. Not working for me.

This worked for me, the app opens normally after restarting and the ads are nowhere to be found! Thanks @adamski90

[czullo]

Any hope for update and fix this?

[appkins]

I fixed this issue in a recent PR for windows #60

[IamKevio]

I am still having issues getting blitz-app-adblock to work on my PC. Installing blitz-app-adblock-win.exe, and then opening the Blitz application normally after that is still causing it to crash out every time. I have also tried the workaround orginally posted by
adamski90.

-Full close Blitz -Run the adblock installer -Then navigate and run the installer.exe file under C:/Users/username/AppData/Local/blitz-updater

Blitz does boot back up without crashing after following those directions, but the ads are still loading up as well.

[majorcyto]

Kevio, that's because the pull request has not been merged yet so you do not have the updated version that Appkins is talking about. @lulzsun has to merge his changes first before it would work for you again on PC.

[lulzsun]

@majorcyto Kevio is talking about doing the process manually. Which is what the pull request does automatically. I've tried doing the same process and it also didn't work on my end. But I'll give it another shot later with the pull request.

[majorcyto]

Ah yeah, I see what you mean. My bad. I tried it manually before and it didn't work for me either. Not sure what is different about his set-up.

[SonicGold]

I fixed this issue in a recent PR for windows #60

I also tried building with your changes, but ads still appear however. I didn't review what the changes were, but I noticed that the installer runs as part of the process now.

[appkins]

Not sure if this helps, but I'm using the version of the Blitz app distributed through winget package manager. After running winget install blitz and running the script in my PR, Blitz runs without ads.

[appkins]

There are some other factors that could come into play. You probably need to do a clean install of Blitz, because I've noticed that Blitz stages new versions of the app with their own asar file to be patched into the application. This directory should not exist if you do a clean install.

[appkins]

So I think we need to identify a new part of the Blitz ecosystem to fully resolve the issue: Blitz Updater.

If you're running this against a Blitz app that has already run, the patcher is most likely in place. The patcher's responsibility is to replace parts of the Blitz app with new files, one of those being the asar archive. The program will either need to patch this archive, or wipe the contents of the update directory. I think both solutions will completely resolve the issue

[gr3ger]

There has to be some sort of integrity check done. Even if you don't repackage the asar and just change a comment block in a hex editor (without changing file size ofc) it still refuses to launch, so I guess we'll have to find exactly where this happens, and then patch it.

EDIT: I tried creating a TTD trace of the main EXE, but when doing that it actually booted without crashing. This makes me think it tried to do some network call before verifying the files, which then timed out (and was apparently fine with it timing out) because TTD is kind of slow. Not sure how helpful that knowledge is, but I guess it's good to know that it most likely gets it's info from the web and it's not a bundled hash value or something inside the application.

The crash always happens after the second window pops up and it establishes a connection (e.g. after the "retry connection" thing pops up if it's having connectivity issues)

I guess the easiest thing would be if someone had an earlier version of the app.asar package that worked with ad blocking to see what exactly changed. And if nothing changed we can at least rule out that it is happening in the JS application.

[gr3ger]

This is the console output that differs between a modified app.asar and the original one.

The following only happens to the unpatched asar file.

With the exception of [10992:0901/141551.759:INFO:CONSOLE(113)] "APP CORE VERSION 1.15.35", source: (113) being added to the bottom of the patched one as well.

This is when launching the application without being logged in.

I will keep investigating

EDIT: If anyone wants to try with older versions etc, you can download them by going to https://blitz-stable.blitz.gg/ and if you want to download a specific version, just put the <Key> value in the path, like https://blitz-stable.blitz.gg/Blitz-1.14.9.exe and it should download. Then just use 7zip or something similar to unpack it without installing, that way you can get the asar file from whichever version you want.

Another thing worth noting is that the application takes three arguments that could be useful. --debug --dev --verbose

Thank man! And It's still showing ads in my case! Hope to get a better solution

[Vaxie]

Well.. This is work for me: Run blitz > Press Privacy > REJECT ALL ADS > SAVE AND EXIT.. Done, the picture its just for proof :)

If it works for you, i will like to hear it!

I don't have the red privacy button on my version, what version are you on?
