I’ve read a few places that the developers are pretty busy with getting Bitwarden browser extensions ready for Manifest V3, so that is probably why it’s slow going on some of the minor bug fixes for now.
Removed the extension (from both profiles I have on this Chrome instance)
Restart Chrome (with chrome://restart)
Re-installed and re-configured the extension to unlock with biometrics and auto-lock on system lock.
When I now click on the extension icon to unlock it, the “Read Fingerprint” Mac window pops up instantly, not giving me even a chance to click on the “Unlock with biometrics” button. (I can’t click that button once the MacOS Fingerprint reading window pops up).
I’d consider this a solution.
I’ll wait and see if it stays that way in a few days of usage.
Update - it’s been about a week since I re-installed the BitWarden Chrome extension and it seems to work fine - it pops up the MacOS fingerprint window instantly and automatically fills in the matching entries when unocked.
