Fatal error with playback when hardware accelleration is enabled.

[rob bindels]

This is the situation:
Data is on a Qnap nas.
Jellyfin is installed on a N150 device, with Windows 11.
Jellyfin version is 10.10.6.

As the CPU is at 100% for playback, I thought to activate Transcoding.
I did select QSV. And then under Hardwarecoding I selected all, I could. And that works.
It even seems, that the GPU is now being used a bit (10/25%)  and the CPU is still at 100%.
But it works.

As soon as I select under Options for hardwaredecoding: Hardwarecoding switch on, I get a fatal error.

This is for instance the Media info from one of the movies I tried:

Thanks ahead for any help. 
As I am the only viewer of the system, Hardware accelleration is maybe not a needing thing, but if I read that others have 10 streams 1080, or 2 streams 4k, I wonder how to do that, if I am instantly on 100% cpu.
