I’ve not seen this issue before, but my entire zigbee network at home crashed today. Not a single device was responsive.
Restarting home assistant fixed the issue, but I’ve never seen this issue before. The start of the logs are as follows:-

The above exception was the direct cause of the following exception:

Any thoughts on what might have caused this ?
