„ERR_EVENT_NOTFOUND for STUDIO_SYSTEM“

Hi there, I get this error message for my player actions. I rebuilt the banks, deleted them, created new ones, restarted… but this keeps popping up.

Any clue how this can be fixed?

Unity 2021.1.22, latest Fmod version, windows x64

Thx in advance

Can you please share a full stack trace of the error you are seeing?
