I'm having a similar issue. Also happens in 1.8 exp1.

[snigdha011997]

Hi @sunjw , can you please provide us with minimal repro project and the particular instance where it happens for further investigation?

[sunjw]

Hi @snigdha011997
I couldn't identify which WinUI 3 component is the key to the crash. "the particular instance" in my solution is the main exe project. There is only one WinUI 3 project. Just start debug and exit the UI will cause the exception. Not every time, but very easy to reproduce.

[sunjw]

And I think it is related to Visual Studio, I try to use WinDbg to attach the process, it won't raise any exception on exit.
