When I try to select any window or screen to screenshare, it shows the selector and you can select a window, but it doesn't output anything. In the logs I get this error:

12:11:56.371: PipeWire initialized

12:11:56.373: [pipewire] Screencast session created

12:11:56.374: [pipewire] Asking for monitor and window

12:12:04.951: [pipewire] Failed to start screencast, denied or cancelled by user
