I’m having issues building a bank in FMOD studio. Whenever I build the bank and add it to the unreal content folder UE will crash, and will continue to crash on startup until the bank is removed.
I have tried using a different version of both the FMOD plugin and FMOD studio, and I have also tried using UE5.0.
I initially thought it could be the length of the directory, however, I’ve now moved to project to a different location (J:\Git\MWStudios) and still get the crashes.
Unreal’s editor logs the following errors:
Error LogPackageName FromPackageNameChecked: Invalid LongPackageName "Content/FMOD/PrivateIntegrationData/BankLookup"

**And sometimes: **
