Slow Operations during Kotlin sync

[LeFrosch]

Description of the bug:

Recently I started to notice a lot of slow operations exceptions when running a sync for kotlin targets. Maybe worth looking into.

java.lang.Throwable: Slow operations are prohibited on EDT. See SlowOperations.assertSlowOperationsAreAllowed javadoc.
