I suggest to install manjaro-pipewire package and reboot, then test again.

done that, clicking on obs studio wont work and when i ran it from terminal it said this

Ok, my last guess. Install nvidia-vaapi-driver to replace the libva-vdpau-driver. But since is an AUR package, let’s make sure things are properly set. From terminal run:
sudo pacman -Syu base-devel --needed
then run:
pamac build nvidia-vaapi-driver-git

It will ask for reboot. Test after that the OBS.

i tried that and it didnt work, but at the end of the second command it shown with this error

Checking keyring… [1/1]
Checking integrity… [1/1]
Loading package files… [1/1]
Checking file conflicts… [1/1]
Error: Failed to commit transaction:
conflicting files:

  • nvidia-vaapi-driver-git: /usr/lib/dri/nvidia_drv_video.so already exists in filesystem (owned by libva-vdpau-driver)

Remove it first
sudo pacman -R libva-vdpau-driver
then do the build.
