Thanks @eskimo, with your suggestion i was able to look for all my 3rd party libraries. Found out that nanopb was responsible for the crash. Removing pods, re-installing them worked for me.

Faced the same crash for iPhoneX 15.5.0
Yes a third-party crash reporter is there. I have used Firebase Crashlytics. But the crash is not so often. I was unable to find the root cause because it never happened on my devices. I have received the crash report on my Crashlytics therefore, i was curious about fixing it once and for all.
The crash happened on iPhone 13, iPhone 12 Pro Max, iPhone 11 Pro Max which indicates it not device specific. But does it due to the slowness of internet while using some activity/process that requires internet??
