I have tried all the above but still failing to start.
Also updating the Zigbee stick, didn’t solved the problem.
The service keeps restarting.
Unfortunatly the log files aren’t being written, so no idee what the error is.
So, I started over and removed de Ziggbee2MQTT and then installed it again.
Unfortunatly, still not te latest version?!?! But 1.43.0, but starting again and working fine.
Did the upgrade again and the issue still persists.
In the log I see now the error:
Failed to start zigbee-herdsman
Set the log level to Debug.
The log output is the following:

No idea why this is so difficult to upgrade.
