Can you attach a logcat file with your crash?

I have a similar issue when changing Orientation, but in combination with the Community Toolkit Popup:

This results in the following Exception:

This came since a couple of Nightly builds and used to work previously, but strangely enough also in combination with changed Orientation. I don’t change it in Code-Behind, but normally in Simulator or on a real Device, both crash.

Was there a change having an impact on changed orientation, lately?

@MAUIoxo that might be different
Can you log that with MCT?

I can't, but in Debug Mode, at least for my issue, I got the following Stacktrace info:

Object reference not set to an instance of an object.

Update on the matter:
I got a suggestion to disable trimming (and AOT compilations respectively) and test again.
And so I did, combined with re-enabling the concurrent GC.

This solved the issue.
The more interesting part - even enabling trimming and AOT, I cannot reproduce the problem again.
I was able to reproduce it at will, by adding either screen orientation, or the concurrent GC option.

This is the log you requested:

Anyway, I plan to accept my miracle and move on.

Disabling AOT did not work for me. I finally created my own Popup now which works in any Orientation
