So, I reverted back to 441.66 SD drivers which I had been using without problems but it kept crashing.
Uninstalled KB4532693 and has been rendering for 3 days straight on 5 GPUs without problems. It might just be a coincidence but Windows’ history in ruining systems with updates is a thing… I personally had to setup my OS again because it crashed and couldn’t be recovered once while installing this particular update.
It might not be visible at first in the update history, in that case uninstall KB4535996 first.
