[BUG] Game crashes after recompilation

[Yehh22]

Information

1. Apktool Version (apktool -version) 2.9.0
2. Operating System (Mac, Linux, Windows) Windows 11
3. APK From? (Playstore, ROM, Other) Play Store
4. Java Version (java --version) "20.0.2" 2023-07-18

So apparently, the app crashes when I recompile it. No modifications were made. I'm certainly the app does not have any protections. The app works fine if I just zipalign and sign original apk directly

If you try with no sources (-s) and then again except with no resources (-r) - how does your test change?

I tried with both -s and -r, still crashes
