Additional information

I use Kotlin Multiplatform

I have found some new info. The error belongs to this part of code in Utils.kt:

[KlassenAI]

Also, if you remove this line, error will not happen. I don't know why, but maybe it will help someone.

This issue was fixed in 2.1.1, please update the library.
