FMOD crashes build on Meta Quest 2

Unreal Engine
1

Hello!

We are trying to fix the following issue related to FMOD that is making our build crash on Meta/Quest 2. (Crash wont happen in Quest 3 btw)

--------- beginning of crash
01-21 15:56:44.364 8165 8377 F libc : Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x0 in tid 8377 (FMOD Studio upd), pid 8165

:
01-21 15:56:45.502 13099 13099 F DEBUG : signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x0000000000000000
01-21 15:56:45.502 13099 13099 F DEBUG : Cause: null pointer dereference

The crash happens in some levels in our game. We are loading some general banks when starting the game but other specific banks we load/unload them when strating each level. (level music, dialogues, ambiences, etc.)

These are our current versions and settings

Platform: Mobile/Android/Meta Quest

Unreal Engine Project settings:

Do you have any hints?

We really appreciate your help.

Resolved via email discussion. This was due to dereferencing a null pointer in client code.

We don’t have any known segfaults (SIGSEGV) on Quest 2, and there isn’t enough information in these sorts of crash tombstones for us to go off unfortunately- but for anyone encountering similar issues in the future, you can get a better call stack by making a Debug build and enabling FMOD’s internal logging:
