Incorrect compiler version

[Gouvernathor]

When typing something as a Sequence or as a UByte, it gets highlighted with the following message : Class 'kotlin.sequences.Sequence' was compiled with an incompatible version of Kotlin. The actual metadata version is 2.1.0, but the compiler version 1.9.0 can read versions up to 2.0.0.
It also gives the path to the stlib .class file, which is in my kotlinc install directory, which is version 2.1.0.
I never installed any other version of Kotlin, so where does the 1.9.0 hallucination come from ? Why does the Kotlin module think this is the compiler version, and how do I make it see that ?

kotlinc -version returns the 2.1.0 version.
I have the JDK installed, javac -version and java -version both return version 23.0.1.

Should be fixed as of #605, please reopen if not

It seems to work, even though the Kotlin extension didn't update. Thanks a bunch !

Yes, that's intentional, the language server updates are decoupled from the extension
