[Bug]: Android IL2Cpp Error

[ds5678]

Describe the issue

This issue is most common on IL2Cpp Android games, but can occur on other platforms too. It has a signature stack trace:

General [Error] : Cpp2IL.Core.Exceptions.LibCpp2ILInitializationException: Fatal Exception initializing LibCpp2IL!

This error occurs because support for analyzing that type of assembly has not yet been implemented in Cpp2IL.

There are plans to catch this error and switch to not exporting scripts, which would allow users to export these games that they previously could not. However, the catch has not yet been implemented into AssetRipper.

This was fixed in one of the previous releases.

Still happens:
