    @maheshmnj I seriously wonder why you're keeping this issue open...
    

    It's clearly the same issue as:
    
#96424
    
#95844
    
#96768
    

    Which was fixed with flutter-team-archive/engine#30835, and was pushed to master.
    
Now only needs to be released to beta and stable.

    @mkay-42069 This issue was reported in production from the firebase console, The ones you pointed out are reproducible locally when closing the app.  Also, the logs don't look similar to this issue.
    

    So I think it's better to wait for the teams input.

    The symbolized stack trace in #96851 (comment) includes a crash in flutter::Shell::OnPlatformViewSetSemanticsEnabled during destruction of the flutter::Shell.  So this is a duplicate of #95844
