[Bug]: AttributeError: 'dict' object has no attribute 'to_dict'

[unclemusclez]

Is there an existing issue for the same bug?

• I have checked the troubleshooting document at https://opendevin.github.io/OpenDevin/modules/usage/troubleshooting
• I have checked the existing issues.

Describe the bug

Unfinished Session Detected

You seem to have an unfinished task. Would you like to pick up where you left off or start fresh?

Select "Start New Session":

Check in incognito mode

That seemed to have worked.
I am running Firefox 125.0.3 (64-bit)

I received the same error again when refreshing the same private browser window and restarting OpenDevin with make run

Starting a new session instead of restoring the old one seems to trigger it.
