Zigbee devices went off and the SkyConnect Multi-PAN doesn't find the tools

[turcsi801021]

The problem

My problem is that all my Zigbee devices are unavailable after upgra 2025.5.0 and 2025.5.1. I can not restore the HA. Is this the problem only in my HA or has anyone encountered a similar error in the last 2 days?
I don't knonw what is the next step. Now all my Zigbee devices are reachless. Nothing works.
I tried to reset, downgrade... everything. The device appears to exist, but it doesn't seem to communicate with any devices.

The adapter is SkyConnect. Here you can see the configuration of it (is it ok or should i change something)?

I am not a programmer, but this looks very interesting:

WARNING in function 'main' in file /usr/src/cpc-daemon/main.c at line #186 : Running CPCd as 'root' is not recommended. Proceed at your own risk.
FATAL in function 'prevent_device_collision' in file /usr/src/cpc-daemon/misc/config.c at line #843 : The device "/dev/ttyUSB1" is locked by another cpcd instance

What does it mean? could you please explain me what to do as a not programmer?
