Note: this looks like it is likely the same root culprit as https://mozilla-hub.atlassian.net/browse/FXIOS-9642 ( https://mozilla-hub.atlassian.net/browse/FXIOS-9642|smart-link ) , but is just manifesting at a slightly different point in the call stack.

Both crashes are happening during app termination after the BVC has been deallocated. This is similar to a KVO-related memory crash that we saw some time ago.
