Your gpu has av1 10-bit encoding capability?
Possibly try to comment out profile=main

Try to comment out profile=0  or edit it to profile=2

I get all presets above to work from the suse15 RPM installation on Leap 
15.6
On the other hand, I don't get vaapi rendering to work from the 31.12 
AppImage, while they work from my 24.11 IntelHW AppImage, except vp9 
10bit that looks distorted video.
