Studio Display troubleshooting

Hey guys, on my 7 days old Studio Display all of the connected devices (excluding the video from the MacBook connected through the Thunderbolt cable) randomly just stop working. All at once. It seems that there is no way to get them running again except disconnecting the display from and re-connecting to the MacBook again. It's also possible to unplug the power cable. Nevertheless it repeatedly keeps stop working. The interesting part is that in that case the integrated webcam stops working as well. Video and sound from any running application still works just fine, just all (internal and external) connected devices stop working.

I already updated both devices, my mac os to 12.5.1 and the display to 15.5. Still same problem. I even started my mac in safe mode and tried to disconnect all of the devices (except mouse and a usb-microphone). Still same problem.

Does anyone experience similar problems? Can anybody help me out?
