I had installed Girls Frontline (com.sunborn.girlsfrontline.en, version 2.0900_375, versionCode 375) in June, and it didn't run. After exploit protection compatibility mode was released, I tried running the game with that enabled. It worked, downloaded the assets, and ran fine.
An optional update, 2.0901_397 (versionCode 397), is available. I updated just now, and the game stopped working (stuck on loading screen). I cleared the cache and user data, (which had been carried over from the working version), and it still didn't work. I installed the same older version that worked from the APK, and it still doesn't work.
With both the older version (375) and the current version (397), the app hangs as the initial loading screen darkens. According to logcat, there is an error:
Unable to open archive file: jar:file:///data/app/~nIVxP0fDGUP2bTCoM0tZyw==/com.sunborn.girlsfrontline.en-01TajNEz7K37CUboGiwv5Q==/base.apk!/assets/Res/Android/AbConfig.txt
There are other errors shown in LogCat, but that's the final one.
Some other games work, some don't, but this is the only one where a previously-working version doesn't work anymore...
Some more details:
Phone: Pixel 6 Pro
GrapheneOS release: TP1A.221105.002.2022112500 (an earlier version was used when the game first worked. I didn't write the version down at the time. I've been keeping up with OTA updates)
