Empty Android app freezes when switching programs

I'm use empty Android application with empty main qml window and build application on windows with Android Qt6.3.1 Clang arm64-v8a. Run on Android 10 with MIUI.

The application can be run either under the debugger or independently. The problem is reproduced faster if you run it under the debugger and run a couple of other applications on your smartphone. If you collapse, expand the application somewhat, or switch to another application and back, a hang occurs, a black screen is displayed, nothing is written to the log. The problem was found on a large application after switching from Qt5 to Qt6.3.1. But the problem was reproduced on an empty application. On another person's Samsung smartphone with Android 12, it does not reproduced.

The run log ends with the following lines:
