The hardware acceleration is disabled in driver. Even using VLC you won't have acceleration for HEVC.

That seems like the opposite of what the quoted Reddit post says:

>those with newer machines needed to either have the HEVC codec from the Microsoft Store removed entirely from [Microsoft Media Foundation] or have hardware acceleration disabled

From this it sounds like it's been disabled at a lower level, but Windows still expects it to be there and so fails to decode streams unless hwaccel is disabled
