Class::Init signatures have been exhausted, using il2cpp_class_has_references as a substitute!

[guochaolinDLKF]

What happened?

使用Unity2021.2.8f1构建IL2CPP后，运行游戏，程序会崩溃，接着BepInEx报错：Class::Init signatures have been exhausted, using il2cpp_class_has_references as a substitute!
但是换成Mono的方式或者2019.4.33版本后，就正常了。
希望可以支持高版本的UnityIL2CPP

Steps to reproduce

使用Unity2021.2.8f1构建IL2CPP

Greetings!

Thanks for all the reports. Since we've been getting the same reports on Discord and other GH issues, I've consolidated all reports into a single ticket:

#474

You can find more information about the issue and a temporary workaround there. As such, I'm closing this issue to favour one central place for the problem discussion.
