It seems like I’m the only person on the planet with this problem, but on a fresh install of Windows 11 with the latest drivers on a Framework 13 AMD 7640U, I am unable to play back video. The graphics driver crashes, sometimes so spectacularly that it hard-resets the computer. Playback works fine on Fedora 39, so I assume the hardware is fine.
Does nobody run Windows on these laptops?
Maybe it’s redundant but did you deleted the driver one absolutely? (Before reinstalling?)
There is a tool to delete all Grafiks drivers.
