How do I understand where exactly this error is coming from? Maybe I just need to understand what "IrClassSymbolImpl is unbound" means.

Disabling incremental compilation, building again, and re-enabling it solved the problem.

Looks like issue

Do you have reproducer?

[Edoardo Luppi]

Nope unfortunately. I've rebuild without incremental compilation and I'm not seeing it again
