Hello, first-time poster so sorry in advance if I break some/any rules.
I’m trying to run FMOD Studio on my 16" MacBook Pro running Big Sur and, all of a sudden, whatever I do FMOD hangs (macOS beachball). It doesn’t crash, after some time (between 10 seconds and 1 minute) it resumes and everything seems to be fine. Until I do something else and it happens again.
This behavior is very inconsistent, but it seems to happen all across the interface.
I tried uninstalling, and also running an earlier minor version (happens with 2.02.05 and 2.02.04) with no luck.
Didn’t see any thread about this so I wonder if anyone has anything to suggest. Thanks in advance.

When I wrote that forum post I didn’t know what was causing it, but now that I do I thought it might be useful to report it as a bug.
