ZHA/Conbee 2/deConz Error

Hi,

Hoping someone can help. So about 3 days ago i set up my Conbee 2 and everything was working fine (Settings > Devices > Add Integration > ZHA) and my first automation was a switch to turn on/off my PC power socket which also worked fine 3 days ago, this morning (day 4) pressed the button nothing happened, logged in to HA and in devices i found under Conbee 2 “Failed to set up” i checked the logs and i had an error ( Error setting up entry ConBee II for zha) and a warning (Couldn’t start deCONZ) tried to find something online to help but didn’t have much luck but what i did find was

first remove ZHA Intergration, delete .db file and then restart HA - This didn’t work
second plug Conbee stick into a PC and flash new firmware - this didn’t work
third combination of both didn’t work - but when i went to set up the Conbee stick all 3 times when i selected “Erase network and set up new” it would just error out and i would have to go with “Keep current network settings”

Tried installing deConz (add-on Store > deCONZ) this would install but not start, and would cause a 3rd error in ZHA.

Everything is updated i even tried restoring to the last knowen working retore but it still did nothing. Please can someone help? to me it sounds like it could be a faulty Conbee stick (i think)
here are the error files
