Heya! This might be caused by either metadata update corruption or the local Collapse game config being broken. Here are some steps to fix it

Resetting the launcher metadata

If you can go to the App Settings, go there and scroll down on the right panel there is "Clear metadata and restart" button, it should do what it says it does. If you can't go to app settings, assuming you use the default launcher location when setting up the launcher for the first time, you can go to %AppData%\..\LocalLow\CollapseLauncher\GameFolder, delete the entire _metadatav3 folder there then restart the launcher

if that did not fix the issue:

Resetting the local game config

On the same folder as above, go to the folder of the region where you have problem in (*Glb where * could be GI for Genshin Impact, SR for StarRail, and HI3 for Honkai Impact 3rd), delete the config.ini file then relaunch the launcher

You will be asked to locate the game next time you chose that region.

if that still an issue, go ahead and on the Collapse' app data folder, go to _logs folder and send us the latest log file from there, we can try to analyze the issue

Hi, i tried both the steps you mentioned but the issue still persists. I also tried deleting all the folders and reinstalling the launcher with no avail.

Here is the latest log file

Do you have a proxy/VPN/CustomDNS setup by any chance? if yes try turning those off and see if the issue still appears. Because for you it seems to happen just like today based on our Sentry dashboard

If you want to try, you can try our staging build that has the code fixes to try mitigate this error You can download it here https://github.com/CollapseLauncher/Collapse/actions/runs/14336740752

Pick the default one, aot or not its fine, just extract and run, do not replace your current installation as it has no mean of self updating

I’m not using either a proxy or a VPN, and I’m using Cloudflare DNS.

I tried both the default and the aot artifacts and both exhibit the same behavior, I'll send the logs from both instances.

default log-2025-04-09-pre1.83.0-id1-11-50-46.log

aot log-2025-04-09-pre1.83.0-id1-11-53-30.log

I'm at deadend, I'll try to summon our resident .NET/XAML experts @neon-nyan @shatyuka

While waiting, can you try repairing your Windows by running these commands in the cmd as admin then restarting your PC

SFC /SCANNOW
DISM /Online /Cleanup-Image /RestoreHealth

Note: only do this if you're not on a modded Windows (custom ISOs), if so, contact your modder for assistance

Note: relates to #721

I created a VM with a fresh Windows 11 install, it has the same problem. I installed Cloudflare Warp VPN in the VM and after enabling it the error disappears, and after disabling it the problem comes back. I'll attach the latest 2 logs

Cloudflare VPN log-2025-04-09-pre1.82.21-id1-12-29-43.log

No VPN log-2025-04-09-pre1.82.21-id1-12-29-56.log

then it's confirmed a network issue, causing the apiResourceProp to be nulled somehow, we though still need to fix the underlying issue to clear up the log data so the user have less confusion

Seems fixed? #720

[bagusnl]

@shatyuka the user tried running the latest AOT build that has the fix for that issue which produces the same error
