1. Open OBS
2. In Sources select "screen capture (pipewire)" -> select a screen ->
everything good
3. click again on the same screen capture source -> select monitor -> crash
OBSERVED RESULT
Crash

No crash

Reproducible every time, I see this already since 5.25.0 at least crashing
Not sure if the bug is in portals, might also be OBS, just had a quick glance
at the crash
