So we had this issue after upgrading our project to UE 5.5, where our project crashes on the second launch, after FMOD assets have been build inside FMOD folder. And we get this errors:
[2024.12.14-13.21.31:052][ 1]LogUObjectLinker: Error: Detaching from existing linker /Game/FMOD/Events/Projectiles/Grenade/GrenadeExplosion while object MetaData None.PackageMetaData needs loading (Standalone | NeedLoad | NeedPostLoad | NeedPostLoadSubobjects | WasLoaded). Setting linker to nullptr. See log for more information.
[[2024.12.14-13.21.31:628][ 1]]LogStreaming: Error: AsyncRoot still associated with Linker
Array index out of bounds: 0 into an array of size 0.
It dissapears when we delete the folders inside FMOD folder, and launch the project again. Then everything is back to normal, until after we try to re-launch our project again. Can this be related to FMOD version (5.4) incompatibility with UE 5.5?
