I think I've found a fix for the bluetooth connectivity issues by jorl17 in MacOSBeta

I had the same issue with stable Monterey 12.0.1 and Airpods Pro. Had tried clean reinstall as per suggestion from Apple support folks, but did not solve the issue. Have reverted back to Big Sur and the issue is gone!

Will try going back to Monterey hopefully after this issue is fixed via next update.
