Start by inspecting com.android.tools.idea.run.deployment.liveedit.PsiListener.kt, especially handleChangeEvent at line 119 and beforeChildRemoval at line 58. Reproduce the PSI change that produces a PsiErrorElementImpl, then determine how the listener handles it. Done means the reported ClassCastException no longer occurs for that event.
