Fenix 7 Pro SS restarts when starting activity or when activating touch

Yesterday my Fenix 7 Pro SS (FW version 16.22) got stuck in restart loop after starting a Run activity. 

After a hard reset, the device is showing the time again, but restarts when I start a new activity. No matter what type of activity.

Besides that, It also restarts when I change any setting related to the touchscreen. So when I change the default setting in the Settings menu, the watch restart; but also when I toggle touch screen on and off in the control menu or by holding START + DOWN.

Is anyone here having the same problem? Or does anyone now a workaround, so that I atleast can start an activity. 

I'm in the middle of a training and now the watch is quite useless to me.
