OBS screen capture freezes after screen lock/unlock (Wayland / PipeWire)

Obs select screen Capture(PipeWire), the OBS preview window displays the image correctly, and the preview updates dynamically with changes on the desktop.
But after screen lock/unlock, obs output PW disconnect:
info: [pipewire] Stream 0xaaaadd461990 state: "paused" (error: none)
info: [pipewire] Stream 0xaaaadd461990 state: "error" (error: no more input formats)
error: [pipewire] Error id:2 seq:21 res:-32 (断开的管道): no more input formats
Click to expand...
after loginning into the destop, the OBS preview stops to update.

Is this by design with OBS ?

Same issue here. Pipewire screen capture always freezes after screen lock and unlock. Either have to reselect from the pipewire source selector or restart OBS. Quite annoying. I'm running GNOME Wayland Arch Linux. Has been the case for at least a year.

Log snippet after a quick obs launch -> lock -> unlock -> reselect which screen to share:
