I have a multiplatform project that compiles successfully. But when I try to run the Compose/Web subproject using jsBrowserDevelopmentRun, I get the following "internal compiler error", without any context about the cause of the problem.
Do you have any idea how can I find the root of the problem?

Besides, jsBrowserProductionRun seems to work OK (but it is too slow to be usable instead of jsBrowserDevelopmentRun).
