Can you provide pubspec.yaml and details about the app, ie what kind of app is it and any features of it ?

I don't think this issue is different from #100777 apart from Another exception was thrown: Instance of 'DiagnosticsProperty<void> exception. Would be good to track this in already triaged and linked issue.
Closing this as duplicate. If you disagree, write in comments and I'll reopen it.

Stacktraces differ significantly

However, if you are sure that the cause of the issue is located somewhere in the first 6 common lines then indeed they are duplicates.
IMHO the reason is located exactly in differing parts :) Some check should be located somewhere there, not at common lines which are mostly simple getters.
