Install Qt 5.15.12 Android binaries, reproduces in all hosts, macOS used in this report. Launch Creator and open project quick controls/controls/texteditor and compile.

Compile is successful, but when deploying to device app is shown on the screen for a short while, but quickly crashes.

Same with location/mapviewer.

Randomly selected widgets/itemviews/address book works normally.

Reproduces also with 5.15.11
