Did you find any workaround?

Since I didn’t want any intent to split-screen, I did this:

public override void StartActivity(Intent intent)
{
    if (Build.VERSION.SdkInt >= BuildVersionCodes.N)
        intent.RemoveFlags(ActivityFlags.LaunchAdjacent);

    base.StartActivity(intent);
}

So it could cancel the previous flag

Not reproducible with Android 11. It didn’t appear as a split-screen.

@YuqinSong Have you tried with a physic phone instead of an emulator? Samsung phones might be affected by this, like my Samsung Note 9 (Android 10)
