No Window Capture - Arch + KDE + Wayland

I have no Window Capture source in obs.
I installed obs via obs-studio-git (from the AUR)
I have tried the following things:
1. Set `QT_QPA_PLATFORM=wayland`
2. `pipewire`, `pipewire-pulse`, `xdg-platform-portal`, `xdg-platform-portal-kde`, `slurp`, `qt5-wayland`, `qt6-wayland`, `gst-plugin-pipewire` and `libxcomposite` are installed

Additional information: I use NVidia (GTX 1650)
(Output and screenshot of sources menu attached)

Go to Sources > Screen Capture (Pipewire) > Create New. There should be 2 tabs: Screens, Windows
