our iOS app facing this repetitive crashing

CDVCommandDelegateImpl.m line 73
__40-[CDVCommandDelegateImpl evalJsHelper2:]_block_invoke

I tried to reproduce the error from my side but no avail. the main problem is this crash event is fairly high for 5 users. mostly FirebaseCrashlytics logs are empty but some logs contain screen parameter that is my Home Screen, can anyone assist me to fix this crash from occurring

Do you have an Apple crash report for this? If so, please post it here. See Posting a Crash Report for advice on that.

It’s hard for me to do anything useful with a third-party crash report, not least because I don’t trust them. See Implementing Your Own Crash Reporter for an explanation as to why.

Thanks for the crash report.

Consider the backtrace of the crashing thread:

Thread 0 Crashed:

6 Cordova        … __40-[CDVCommandDelegateImpl evalJsHelper2:]_block_invoke + 56 (CDVCommandDelegateImpl.m:73)

I’m not a WebKit expert [1] but it seems pretty clear that you’ve run WebKit out of memory as a direct result of calling -evaluateJavaScript:completionHandler: in frame 5.
