How to debug "A problem repeatedly occurred"

Some of our users came across this "A problem repeatedly occurred" issue when they were trying to access our site on Safari on iOS 15.6.1. I tried to use an iOS simulator on XCode to replicate this issue but I couldn't find a simulator for iOS 15.6.1 on my XCode but only one for iOS 15.5.

My questions are:

  1. How to get an iOS 15.6.1 simulator on XCode?
  2. Once I replicate this issue on a simulator, is there a way to debug this? Or is using a simulator the best way to debug this issue?
