Context: We have currently 2 AMD GPU PCs in our lab, since KB5082417, the 9060XT rig is fine, but the 9070XT machine became essentially impossible to play and even watch videos without the driver crashing, even sitting still on desktop. Driver version 26.3.1, automatic driver installation always off since the dawn of time.

Tried to make an in-place upgrade but the situation got worse - now Start menu wont open by keyboard or clicking on it, but opening it through the Search Bar is fine. Event log full of WindowsUdk errors. SFC -scannow made no difference

Everything returned to normal when booting in safe mode and running DDU from it. Zero issues now.

KB5083769 is also a prime suspect.
