Help/Support Il2CppDumper Error: System.InvalidOperationException: Sequence contains no matching element

[Happy Secret 3.7k iPad Pro (2nd gen) 16.2]

Need some help. Not sure why consecutive two games hit this "System.InvalidOperationException: Sequence contains no matching element" message. 

1. Lamar-Idle Vlogger
2. Frozen City

Both use UnityFramework file and global-metadata.dat file as input to https://armconverter.com/il2cppdumper/

Below is the sample result for Lamar-Idle Vlogger

========

Il2cppdumper did not produce any files. Probably something is wrong with the executable or metadata?

Is it I am missing some important skill or knowledge ?

Both game are under Hack Request, trying to see if I can find a solution. Unfortunately, blocked by this.

I think maybe it using new unity version so current dump isn't supported yet. Or encrypted metadata

@Laxus What is the solution?

It could be protected global metadata or unsupported unity version. 

Try frida-il2cpp-bridge module to dump the app at runtime instead:

iGameGod got a new feature - Dumping iOS Unity's global-metadata.dat from Memory/Runtime using iGameGod. 
Let me see if it helps or not

It does work I tested, not sure about non-jb part
