Random VerifyError for Kotlin jar #75

I've tried obfuscating a Kotlin Minecraft plugin. The VerifyError occurs randomly on methods or classes after obfuscation, requiring multiple attempts to avoid the issue, but some methods or classes might remain unchecked.

I'm not sure if it because that my plugin is written in Kotlin.

The stacktrace of the obfuscated jar
