This could be caused by a file that was imported.
You can try temporarily moving the cache folder to the desktop, and reopening the app. If it works, you can try moving files / folders back one at a time to isolate which imported file caused the issue.
The cache folder is located here on MacOS:
To easily get to this folder, use the GO menu at the top of the Finder, and select GO TO FOLDER, and copy that address into it.
If you do find that a MIDI file caused the issue, please upload it so that I can test the issue it was causing - Thank you!
You can move it back where it was, just without the problem file.
Or you can move just whichever files back that you want to keep - it’s up to you.
Thanks, it's working. I moved all the folders on my desktop (There's no folder called "cache" so I moved all of them: Unity, visual design, audio files, etc...).
What do I do with the problem folder when I know which one it is?
