It’s hard to be sure because your code listing is so badly munged (1) but this looks very similar to the problem discussed on this thread. Note that frames 3 and 2 in your crash report match frames 6 and 5 in the snippet in my latest post on that thread.

(1) In future you can make your posts more readable by using a code block (the <> button) for code snippets and the text attachment feature (the paperclip icon) for full crash reports.

If you have Firebase/Performance in your pods, that's the problem.
Removing it you will fix the issue.

Thanks @Eskimo.. You saved the day. Was debugging who is observing the state. Got to know GoogleTagmanager and Firebase Performance SDK is reason of crash behind the frame 3 and 2.. I removed Performance SDK, The Crash is not replicable now. Also, I reverted GoogleTagManager (7.2.0) to GoogleTagManager (7.1.4) This case also the crash is not happened.

Moved to production with these changes which resolved this crash.

Thanks for ur reply @esikmo & iijjj
