I'm using kotlinx serialization on kotlin 1.8.0 but I get this error when building which did not occur on 1.7.20. I should also mention im using compose for web, but I dont think that is causing this error.

e: org.jetbrains.kotlin.backend.common.CompilationException: Back-end: Please report this problem <https://kotl.in/issue>

Compose is an IR plugin rewriting IR and apparently, the serialization plugin is applied after compose processing the (bad) rewritten IR.
