I was able to do the upgrade on a different installation:

Python: 3.8.5
Nautobot: from 1.0.1 to 1.1.0b1
Plugins installed: Chatbot

I was able to get back into the server. registry["nav_menu"]["tabs"]["Plugins"][list(registry["nav_menu"]["tabs"]["Plugins"])[-1]] is a set, so when attempting to access ["weight"], it produces that error.

(Pdb) pprint(registry["nav_menu"]["tabs"]["Plugins"][list(registry["nav_menu"]["tabs"]["Plugins"])[-1]])
{'nautobot_device_onboarding.view_onboardingtask'}
(Pdb) pprint(registry["nav_menu"]["tabs"]["Plugins"][list(registry["nav_menu"]["tabs"]["Plugins"])[-1]])["weight"]
{'nautobot_device_onboarding.view_onboardingtask'}
