[contributing] Completion error in intellij after 2.0.0-RC3

[Chuckame]

Describe the bug Since kotlinx.serialization 1.7.0, I'm unable to contribute as all the kotlin standard library is missing the completion, and/or have the standard library missing from the classpath, which makes all the listOf, apply, to and more to be red. No issue when going back to 1.6.3. I don't know if it's a misconfiguration of the library or my computer, but this is the only project having issues (regarding 10-15 other projects), that's why I'm opening the issue here.

I tried everything, even reinstalling intellij, emptying gradle's cache, remove shared indexes, etc. Also tried with multiple Java runtimes from 17 to 21.

Do you already had this issue?

To Reproduce Just checkout 1.7.0 or master.

Environment

• Kotlin version: lib's version
• Library version: 1.7.0+ (1.6.3 ok)
• Kotlin platforms: all
