It's only a side-effect. The real cause is missing video stream in the pipewire capturing. Unfortunately this API has somedrawback, especially when the video acceleration is used. Still it's not a HyperHDR issue.

@artempl you can try latest PR that implements hardware acceleration for capturing Wayland using Pipewire #556 Still it's up the Pipiwire to provide valid video stream and don't break (or at least start the auto-resume procedure) it e.g. when the application switch the video mode.
