iOS build crash after startup

Hey, guys,
We have a published game on the App Store and since last month I am not able to build the game on iOS platform. We are using:

• Unity 2020.3.2 LTS
• Unity IAP 2.2.2
• GoogleMobileAds 5.4.0
• FireBase 7.*.*
• CloudOnce 2.7.2
• iOS target: 11-12-13-14

Ever since last month, I am facing this issue that the game stops at a specific moment while initializing everything(firebase, IAP, play services-analytics, etc.). In XCode, I get the following log and the game stops functioning and freeze on the loading page:


And the last logs are :

terminating with uncaught exception of type Il2CppExceptionWrapper

The weird thing is that everything works pretty well with the android build, but in the iOS build, I'm getting this.
Also, I'm pretty sure there is something up in connecting to wether Firebase, Unity IAP, or other ads services while trying to catch some data online. Because when I try to play offline the game is functioning great and when I start the game online this freeze comes up.

What I have tried to do until now:

• Reinstalling and reimporting different versions of IAP, Firebase, Google mobile ads
• Changing Unity versions to 2020.3.0 and 2020.3.6
• Changing some build phases (which is a pain in the ...)

I appreciate any help. Thank you so much.

 

hey, have you found a solution to your problem

 

Also looking for a solution to this problem.

 

My problem was solved when I installed a lower version of the firebase packages. I believe last time I was working on that project this problem was fixed in tha latest version of firebase (I guess version 8.x). Looked like it was all because of firebase initializing it was getting hung up in the middle of api request and I really was not able to find the exact problem. I even tried to contact the firebase support but they could not help me either.
