Is there any way to bypass this problem?

Not on the client side.

It is not.

iOS 13.2 was just released and I recommend that you encourage your users to upgrade.

Seemingly out of no where I have just started to see this crash pop up as our #1 crash in app. It is a repetitive crash for most users that see it.

It seems that the issue is still around or a new one creeped in? I can see a number of crashes in Crashlytics on iOS 15.5.0.

This thread is about a crash where the topmost stack from is qlog_abort_internal. Your crash is quite different. Please start a new thread about it. Tag your thread with Network so that I see it. Also, please include the full crash report, per the instructions in Posting a Crash Report.
