I got this answer to resolve the Monterey issue:

“ Please close BIAB and navigate to Applications/Band-in-a-Box and rename the Preferences folder to Preferences2, then try to run BIAB again. Band-in-a-Box will re-create these files, so it is normal for them to come back later.

Please note that macOS Monterey is not yet fully supported.

Thank you,
