Crash during initialisation - processServerOperation -> setSavedURLPatternList #1482
Description
Describe the bug
We just released our Flutter App after integrating with Branch SDK (via flutter pkg v8.3.2: https://pub.dev/packages/flutter_branch_sdk, iOS SDK v3.7.0) and today we noticed some crashes in iOS with the log below.
For some users, it looks like Branch is having a hard time trying to save url pattern (regex) during the initialisation of the SDK.
Steps to reproduce
I could not reproduce it myself, nor our QA during our internal testing period, but we've seen the following log in our Crashlytics after having the app published for few days.
Log:

Expected behavior
The app to not Crash, even if there is a problem on Branch's SDK initialisation side.
