Volume Hash Mismatch leads to apps crashing after clean install

I've spent a week trying to get my 2019 iMac back. The repeated volume hash mismatch warning and web pages and Safari crashing led me to act. I had a back up so reinstall, but only Mojave. Downloaded on MBA Monterey 12.4, erased iMac hard drive and performed a clean install - except there was ALWAYS an error. Went back to Mojave and worked up to Monterey.

Used Migration Assistant to load from the back up. Looks good except, all but Things and Twitterific won't load. Got the icons but no substance. Error is Namespace CODESIGNING, Code 2. Also noticed I can't get Monetary 12.5 because "can't load data from the Apple Software Update Server."

Suggestions?

iMac 27″, macOS 12.4

I'm an idiot. I looked through my 2015 MBAir and decided it had most of what I needed on my iMac so I did a migration from the MB ti iMac. Smooth! But I still have a whack of apps that show the CODESIGNING, Code 2 error.
