The setup is:

1. MAUI Android
2. ScreenOrientation = ScreenOrientation.Portrait set to the MainActivity.
3. Building in release.

At real physical device, using adb logcat -d > log.txt the following error can be seen:
Fatal signal 6 (SIGABRT), code -1 (SI_QUEUE)

With those libs: libmonosgen-2.0.so, libmonodroid.so

1. It crashes in release only.
2. It doesn’t matter how the screen orientation is set. (annotation or overriding onCreate)
3. Disabling “concurrent GC” fixes the issue.

I would like to know:

1. How to fix the crash,
2. Or if it cannot be done – is there another way to force screen orientation?
3. Or if it cannot be done – at least some reassuring words that this little fix I found is actually something harmless, and I wont have to pay for it in the future.
