Despite still running Tiger on a G4 ibook for a network task, illustrating my respect for old hard & software, BS runs fine on my MBP i9 16" 2019.
I'm very wary of new OS and update releases and tend not to be an early adopter, but I bit the bullet with BS, love it.
Those moaning should format & clean install,test then install your apps etc one at a time, testing each time - you may identify the culprit.
If it's knackered after a fresh install you likely have a hardware issue.
