Yes, the Notation issue is a known problem. It worked properly in the pre-release version of Big Sur, but not on the official release (which we don't get in advance - we get it the same day you do).

The M1 chip is not officially supported yet, but from our testing Rosetta 2 typically works well - we have one of the ARM Mac Mini's in the office.

If you don't mind, would you be able to email some files to us so we can try and find a better fix? If you go to to Applications/Band-in-a-Box/Preferences, please attach those to an email and send them to support@pgmusic.com for our developers to analyze. Then, to solve the crash issue, delete the contents of the Preferences folder (after emailing the files to us) and try running BIAB again.
