Is there a pattern to this? I would suggest:

1. Delete the Preferences files to return factory settings, like you've done before.

2. Install this new build (NOTE this does not have big sur fixes, however it does have a fix for a crash).

3. Run Band-in-a-Box. Please report back if it's still happening, and if there's any kind of pattern that you can see.
