Roblox studio crashes when a SurfaceAppearance is inserted

  1. Insert a part
  2. Insert a SurfaceAppearance under that part
  3. Roblox studio shows a popup that SurfaceAppearances can’t be inserted (expected)
  4. Roblox studio crashes (not expected)

Expected behavior

Roblox studio doesn’t crash and dismisses the popup

We’ve just shipped a fix for this, thanks for the report!
