Critical Bug in URP post processing. Stops ability to view prefabs in prefab edit mode.

Hi,

When I open a prefab to edit in the editor I get this error (pasted stack below). It’s 1) annoying, and 2) preventing me from editing UI in prefabs which is super not useful. Anyone else seen this? Anyone know what the problem might be?

If I disable the post processing Volume component then the problem goes away. Seems like a bug in post processing in the URP.

Also experiencing this issue. Made a temporary workaround to only enable the volume when playing.
Is it possible for me to track this case? I can’t find it in the issue tracker.
