Advanced Zigbee Troubleshooting on Homey

So ive updated my SHS to 12.12 and overnight my zigbee is dead.

It started with my Tuya brand devices but now i cant add any zigbee devices either. I have snapshots of pre update but on boot it brings back 12.12.
I did disconnect the ethernet during boot but this didnt really solve the issue!

These are the messages im getting in the shs log and when i try to use a device i get a timeout message and when i try to add a device i get an unable to connect.
I suspect the bridge may be faulty but i could add zwave so only the zigbee chip.

I restored an older snapshot snd the issue remained BUT the zigbee stack warnings in the image did not populate the logs.

Few question. If i change/replace my bridge (add new one first) then remove the old,
Will all devices drop offline?

Has anyone seen these messages before? Any clues?

Much appreciated. Thanks
