How do I recover from a hard lockup on the MK3?

The screen on my MK3 is frozen. Holding the light button for 30s is not forcing a power off. I’m on version 19.34. Does anyone have any ideas on how to reset the device?

I have the same thing now. I unpacked the watch from the box and connected it to the PC, everything is OK, after he offered to update the firmware to 19.34, I updated it and then the screen started to hang when connected to the PC (charging is going on) On the PC there is a sound of connecting the device and disconnects it and all actions are repeated =( . I hope this is a bug in the firmware and it will be fixed in the next release. P.S. if you disconnect the charging cable and wait a bit, the watch will return to normal, or you can simply restart it via the "light" button
