I work with a team developing a game on UE 5.5 and FMOD Studio 2.02.26 and something has caused a crash for every team member’s build.
Unreal opens fine the first time but if you close and re-open it crashes immediately and produces these errors.
Looking through the forums it sounds very similar to this issue. UE 5.5 project crashes on second launch - #3 by Ravenlord
This is the crash log from Unreal:
Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Containers\Array.h] [Line: 783]
Array index out of bounds: 0 into an array of size 0
