Ventura 13.1 killed my iMac

Installed Ventura 13.1 on 2019 iMac Retina 5k with 128 GB RAM tonight. EVERYTHING slowed to a crawl. Bluetooth connection to keyboard and trackpad drops repeatedly. Wi-fi connection drops repeatedly.

Tried direct connection on keyboard and trackpad, direct cable to internet, reinstall of 13.1 in safe mode, and removing all apps running in background. Minimal improvement since wired connections eliminated the time the os was spending trying to reconnect. Still takes minutes to do trivial tasks like open an app. Too slow to use for anything.

No problems with Ventura 13.0. Anyone seen anything like this? I’ve never had a problem with an Apple OS update before.

I couldn’t get anything to work. Consequently, I erased and formatted the hard drive and installed Ventura on the clean drive. Recovered everything from a Time Machine back up. Migration Assistant detected an application that was incompatible (Panopto - used to record classes I teach). It had a program that ran in the background. I don’t know if that was the problem or not. The migration took about 16 hours, so I am just now starting to see if all is well. So far, so good, but I haven’t done much more than finish the migration. I have a MacBook still running Monterey, so I’ll remove Panopto and try to upgrade to Ventura to see if it goes smoothly.
