ZHA and Conbee II integration error

Hello Everybody. Need help.

I have tried to setup integration of Conbee II with ZHA. I put to configuration.yaml:

zha:
usb_path: /dev/ttyACM0
radio_type: deconz
database_path: /config/zigbee.db

Then I tried to connect my Conbee with end devices but it failed and I decided to remove integration.
Now I have in Integration tab ZHA integration and I can’t delete it. And each restart I have the error: Setup failed for zha: Unable to import component: No module named 'zigpy.config'
