Seeing the exact same issue - why it says "UICollectionView.." is beyond me, probably a bug. But did you figure this out? It does work if you set a symbolic breakpoint for NSCollectionViewFlowLayoutBreakForInvalidSizes

I've got the same issue in our app. We get infrequent crashes in scrollWheelWithEvent and we have absolutely no idea how to prevent them.

Were you able to find a solution to this?

That doesn't work. AppKit still seems to handle any mouse movement over a NSTextField even if there's another view on top.

Truly fed up of the productivity killer called Notarization. Frequently we find that it can take up to an hour at times. Frustrating to say the least as we need to urgently prepare a bug fix after a public release and suddenly notarization won’t complete within a reasonable period of time.

Same here. 3rd party frameworks that worked fine up until 12.2 have stopped building / code signing. Going to have to downgrade to 12.2

Do we have an update on this? Same issue here. Users on 10.11 cannot install our app. Moreover, Big Sur users are getting other weird errors such as "This app cannot be opened".

Same here. Our users on Intel macs are reporting that they can no longer install our app / updates as they get this prompt. I've been unable to figure out what's going on. One user said re-installing Big sur fixed it for them but others have had no luck doing that.
