Updated to 14.7 and garageband won't open

Used OCLP to update my 2010 iMac to Sonoma 14.7.3 Everything appears to be fine but if I open Garageband and attempt to start a project with an audio track I get the error "unable to initialise graphics. This typically happens when running inside an unsupported virtual machine"

This was all I upgraded for, in order to be able to use the latest features of garageband. Any ideas how to fix it?
