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?
After all that’s been said, try redownloading the Windows 11 installer and put it on a different USB drive. Trying to eliminate the possibility of a bad Windows install.
