A crash occurs when starting either the Landscape Painting Mode or Landscape Sculpting Mode tutorials. It crashes even if a landscape is already in the level.
This is similar to [Link Removed], however the specific repro steps in that have been verified fixed, while this crash still occurs
Result: crash
