OBS says "Failed to open NVENC..."

The OBS error says "Failed to open NVENC codec: Generic in an external library. Check your video drivers are up to date. Try closing other recording software which might be using NVENC such as Nvidia Shadowplay or Windows 10 Game DVR."
I installed package:
1. linux-zen 6.0.9
2. linux-zen-headers 6.0.9
3. nvidia-open-dkms 520.56.06-10
4. obs-studio 28.1.2-1

I use xorg session and I installed all updates via "pacman -Syu"

Any solutions?

nvidia-open does not yet support NVENC afaik, try the normal nvidia-dkms kernel modules.

And also you'd may prefer nvlax-git instead of (unpatched) nvidia-libs.
