Alternative Launcher doesn't launch Falcon BMS 4.35 anymore

[Warmoer]

Alternative Launcher worked perfectly a week ago, but tonight when I wanted to launch BMS the launcher just closes and BMS does not launch.

Windows Event Viewer summarises it as follows: Faulting application name: Hub.exe, version: 1.6.0.0, time stamp: 0x5fe0339c Faulting module name: KERNELBASE.dll, version: 10.0.18362.1316, time stamp: 0x7a6bfa05 Exception code: 0xe0434352 Fault offset: 0x001146d2 Faulting process id: 0x4e2c Faulting application start time: 0x01d6f24e43ff5b79 Faulting application path: G:\Games\Falcon BMS 4.35\Bin\x86\Hub.exe Faulting module path: C:\Windows\System32\KERNELBASE.dll Report Id: 3952c106-0d6d-4a64-8bb3-1db1ff9b5c08 Faulting package full name: Faulting package-relative application ID:

Any ideas on what may be causing this? I saw at least one other person having the same issue on the Benchmark Sims Forum: https://www.benchmarksims.org/forum/showthread.php?41176-Alternative-Launcher-doesn-t-launch-(

This is a CLR exception being thrown from KernelBase.dll from the looks of it. I recommend we all start looking through that.

@Warmoer Could you please include a few more details such as what theater and any other error code type details that it tells you (if any).

I'm looking into this myself however I've been unable to replicate the issue yet.

[Hawkeye4040]

I just grabbed a full fresh copy of the latest version and it still launches BMS 4.35 fine for me here. It seems likely we'll need more information here to see exactly where the issue is and what's happening.

[Warmoer]

I am running a vanilla BMS 4.35 with no mods or theatres. There is no error message per se; clicking on the launch icon drops the app to the desktop after a second and that is it. This info is provided with the event: `Fault bucket 1813022862042814945, type 5 Event Name: CLR20r3 Response: Not available Cab Id: 0

If there is something more helpful that I can provide, please let me know how to generate that and I will pass it on. I will look into the Kernelbase.dll issue in the meantime as well.

[Warmoer]

I uninstalled 4.35, reinstalled, added the Alt Launcher files again and copied my User files back and now it appears to be working. Not sure what broke and why, but it seems to be working for the moment. If anything happens again I will let you know - thanks for looking into this.

[Hawkeye4040]

That's actually very useful information thank you for sharing that.

Hmmm, I tried rerunning AL as admin. It still crashed, but this time I didn't get the stacktrace above. I did get this though:

Falcon BMS.cfg is empty after the crash, so I'm guessing it might be related to that. Note to self: Make backups.

[lstor]

I think I know what caused it. I was running a Steam update in the background and ran out of disk space. I'm guessing the code writing the config files don't handle the no space exceptions gracefully.

[fritzcloud]

Having the same issue weirdly, I remember it working fine a year ago or so. I have diskspace.

It still launches without setup override.

[Hawkeye4040]

Yeah @chihirobelmo we need to implement that diagnostics code I added everywhere. It'll make it orders of magnitude to hunt down issues like this.

[fritzcloud]

Still having this issue, some help would be appreciated :)

[chihirobelmo]

Can you try this version to repro crash? There should be an error message dump poping up

AL162.zip

[Hawkeye4040]

This looks like something new in Windows Security. A band-aid patch to a security issue. This change in the libs for windows has affected a lot of stuff. A lot of programs aren't able to access certain parts of the file system now. There is a different way to do it. The only problem is this is like the third time (that I can recollect) that they've changed this. So now we have to hunt down another workaround here.

All of this is assuming I'm correct about this being the same issue of course. This looks like the same issue that is plaguing WDP right now also. Stuff that I knew for a fact that was working the last release on that, stuff I know he would have no reason to touch/change. Suddenly magically broken. All of this around the same time as said band-aid patch security update. Still, that's technically an assumption but without any strong evidence pointing elsewhere, that's where I'm going to dive in and start looking. I'm at least a little more confident in this seeing that it's an unauthorized access exception being thrown here.

But first I need to set this all up on a laptop or something off to the side with an experimental instance of BMS so as to not mess up my good logbook in the event that something gets messed up. I have to do all that all over again so this one may take me a while. This is all in my free time...

Strongly recommend backing up you're entire "user" directory in BMS if you haven't already.

We fixed it together in discord a couple days ago. The problem was that my Anne Pro 2 keyboard was causing the configuration file not to write for some reason. Unplugging the device, hiding it using "hidhide" tool or using version AL162 works.

I am going to have to look into this keyboard specifically. That is a very interesting issue. I'll run that on my other machine I'm setting up off to the side to debug a lot of stuff with this and BMS without it affecting my personal saves or having to spend hours restoring stuff when I want to fly. I'll run it on there as soon as I can when it's all set up. That's happening in my spare time so it might take me a little bit.

[Hawkeye4040]

@chihirobelmo Have you run this one yet?
