[Kotlin] java.lang.NoClassDefFoundError from kotlin coroutines

[min2]

Hello I am trying to decompress .imy files in a game called Criminal Girls.
After a few days of googling, I finally found a Kotlin script, but when I try to run it, I get a java.lang.NoClassDefFoundError in kotlin coroutines.
I did a few googlings but failed.
Does anyone know anything about this?
I will also attach my project and error log below
