iMac14,2 – Lot of problems

I have installed OCLP on a couple of Macs with varying results; All from perfect to disaster. At the moment I'm helping a friend with his iMac14,2 (27-Inch i5 3.2 (Late 2013) with 16 GB RAM and 1 TB Samsung SSD). This machine: https://everymac.com/systems/apple/imac/specs/imac-core-i5-3.2-27-inch-aluminum-late-2013-specs.html

I have tried Ventura, Sonoma and Sequoia. The installation goes through, but then "stuff" alwas happens. Eg applications crashes, Finder crashes, Freezes, etc. I can't explain why.

I just want to check if someone have any idea about this particular machine?
