I'm getting an IDE error java.lang.RuntimeException: Broken stub format, most likely version of kotlin.FILE (kotlin.FILE) was not updated after serialization changes just all the time - stacktrace in thread. Anyone know what I might need to delete to fix it?

I'm a bit lost as to where the issue is, but as the stack contains com.intellij.openapi, org.jetbrains.plugins.gradle, org.jetbrains.plugins.groovy I'm guessing it's actually not so much an issue with IntelliJ's Kotlin support / plugins as a problem with one of those plugins that happens to have been written in Kotlin... so unsure if this is not kotlin but kotlin colored or not!

You might try invalidating cache and restarting

does cache invalidation help you or not ?

[Rob Elliot]

Doing the whole lot on repair IDE did seem to fix it, thanks for pushing me to do it, sorry for bothering you

[Daniel Pitts]

It was no bother. Glad it worked!
