Zigbee2MQTT throwing errors in HA Core logs

[daproject85]

Description of the issue

I’m just about at the end of my ropes and not sure what is going on. When I change the name of a device with in zigbee2mqtt interface, i get the following errors and warnings in my HA Core logs. I have posted the screenshots of the errros and my version of HA. For record I am using a brand new SLZB-06 coordinator. I had the same issues with my Sonoff dongle as well. At this point willing to pay someone for helping me fix this. I completely uninstalled both the mqtt broker add on in HA and z2m add on. I’m still getting these warnings and errors . The device works, i just dont know why this happens
