I looked online trying to find the sourcecode for Kotlin Native, and I can't even find that method it is crashing on. So if anyone has any ideas would really help me out? I have a relatively simple module I have just created, and for whatever reason it wont build

It's a long shot, but there's some mention of KotlinIrLinker in the stack trace. Aren't you using the new IR Kotlin backend which is in beta, maybe?

The issue came about because I wasn't using common coroutines, but just for JS, Android and iOS. I had included "org.jetbrains.kotlinxkotlinx coroutines core1.4.2-native-mt" for each platform, but I had to change iOS to be core-native-1.3.8
