I got the same error, but only when opening some of my sessions created today (probably created before 1.1.8). New sessions created after 1.1.8 work for me and older sessions from few days back also open without this error.

I think this was due to a breaking change in answer question tool outputs, I think there was a case an invalid answer could appear which caused these issues and broke a lot of type assumptions (that are now reasonable).

I doubt this will impact many people tbh since it isnt possible going forward, only certain old sessions w/ invalid data will have it

[damian-zajaczkowski]

I experienced a similar issue with version 1.1.8. I "resolved" it by disabling autoupdate in the opencode.json configuration file (by adding "autoupdate": false) and installing version 1.1.7, which works without the fatal error.
