include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.
I recently upgraded to the RX 6800
What discrete GPU were you on for your platform prior to the RX6800? When using DDU, remove all GPU drivers(Intel, Nvidia and AMD) in Safe Mode then manually install the latest GPU driver in an elevated command, i.e, Right click installer>Run as Administrator.
