Android crashing when rotating a flyout page

[Brosten]

Description

I'm opening a new issue on this topic, since the existing once are incorrectly closed.

I use a flyout page and when rotating the screen, ~1 time out of 10 the app crashes.
The error message is something like:
androidx.drawerlayout.widget.DrawerLayout.getDrawerViewAbsoluteGravity
java.lang.ClassCastException: androidx.appcompat.widget.LinearLayoutCompat$LayoutParams cannot be cast to androidx.drawerlayout.widget.DrawerLayout$LayoutParams

Other similar, closed reports:
#20858
#18161

Steps to Reproduce

1. Create a maui project with a flyout page
2. On details page, put some random content (e.g. I added 50 lables within a VerticalStackLayout).
3. Rotate the screen a bit back and fourth. Eventually, the app will crash with the above error, or something similar.

No response

Version with bug

8.0.82 SR8.2

Is this a regression from previous behavior?

Yes, this used to work in Xamarin.Forms

Last version that worked well

Unknown/Other

Affected platforms

Android

Affected platform versions

All versions, what I know of

Did you find any workaround?

From what I found, setting
FlyoutLayoutBehavior = FlyoutLayoutBehavior.Popover;
seems to prevent the crashes. But you also loose the visible flyout that can be nice to have, at least on landscape tablets.

@Brosten I tried to verify the issue but it didn't reproduce. Can you share a sample project with us so I can investigate further? Looking forward to your reply!

@jaosnz-rep: Sure, her's a repo.
RotationCrash.zip

I run this on an android tablet emulator, running Android 14 (API 34)
After rapidly rotating the screen in random directions, it crashes after 5-10 rotations.

I can repro this issue at Android platform on the latest 17.12.0 Preview 2.0 (8.0.90 & 8.0.82& 8.0.80).
