Yep, I am seeing this as well, rolling back fixed the issue. Currently, I can't get any more information out of the logs than you've already provided.

I can confirm that the Access Violation only occurs on one of my WinUI 3 Desktop apps, my other one, for whatever reason loads fine after the update. So I'm assuming there's some interaction happening somewhere that's causing the issue.

We're experiencing this too; rolling back for now.

Just to put the workaround here as well. You can get past this issue by turning off the "Enable in-app toolbar" from the XAML Hot Reload under debug settings.
