Zigbee stick not working

Installation Home Assistant OS

Hello,
Since 1 week my cc2531 stick stops working. I don’t know what the error logs means.
Anyone knows what to do?
It gives me this error:

Those sticks are well known to be pretty terrible. From time to time they lock up and need taken out of the computer for 30+ seconds to reset, or possibly even re-flashed.

The best thing to do is buy a CC2652 based stick to replace it.

Thanks. I will take it out and try. It’s running for 2 years very stable.
I also have a sonoff sigbee bridge with tasmota. Is that better than cc2652?

It’s better than the CC2531, but only just. It too is pretty terrible. It’s nowhere near as good as a CC2652 based device.
