It looks like #8295 made it so that we're now exposing a frozen SectionedResults from @ObservedSectionedResults. You can work around this by explicitly calling thaw(), but we should maybe see if we can avoid this.

I am currently experiencing the same issue, but downgrading to 10.51.0 unfortunately does not help. Using @ObservedSectionedResults works correctly; @tgoyne where and what would you thaw() exactly to work around the problem?

[nirinchev]

You need to call thaw() on the results instance before you call .observe() on it.
