I was also getting the same error everytime both in Windows and Ubuntu. Then I suspect that the source of the error may be my locale or language.
Changing locale didn’t help but changing display language solved the problem both for Windows and Ubuntu. My previous language was Turkish, and changed it to English. Apparently this is a uppercase-lowercase Turkish I problem in the CompilerOutputParser.CATEGORIES map: I -> ı, İ -> i
Could you please check daemon status, is it on? (Settings | Build,... | Compiler | Kotlin Compiler | Keep compiler process alive...)
If so, could you please try with the disabled daemon.
The same error occurs with Keep compiler process alive between invocations setting enabled, and disabled. Version info:
