Display and buttons frozen and unresponsive

My Descent Mk3i 51mm has become unresponsive and freezes a few seconds after turning it on.

The only thing I can do is long hold the power button to turn it off. Turn it on again and within seconds the display freezes again and the device becomes unresponsive.

I do not have enough time to get to and activate a reset of settings in the menu before the device is frozen again.

Has anyone else experienced this? If yes, how did you solve the issue?

Device is updated to current SW version:
