Would anyone understand what this error means?

Execution failed for task 'compileKotlinIos':

Compilation failed: Deserializer for declaration public kotlinx.coroutines/SingleThreadDispatcher|null[0] is not found

looks like it comes from here? https://github.com/JetBrains/kotlin/blob/master/compiler/ir/serialization.common/src/org/jetbrains/kotlin/backend/common/serialization/KotlinIrLinker.kt#L451

Tried skimming this file but I can barely understand what’s going on 😬
