Cant start VR with valve index

With a valve index on a i7-2600k plus I can’t turn VR on on my desktop. (Got it to work on my laptop).
Currently 1.16.13 but it never worked on this pc.
I have an open XR error message.

I turned on steam VR beta. I tried other game that use open xr with success.
Checked registry it looks all right with steam open xr path.
I have tried with and without dev mode on.
I have even uninstalled steam completly and same.
