Short description of error
When I render using Workbench Engine and object is in sculpt mode, the object disappears in render and sometimes Blender crashes

Exact steps for others to reproduce the error
Based on the default startup

  1. Switch to the Workbench Engine for rendering
  2. Enter sculpt mode for the default cube
  3. Render image, it's ok
  4. Sculpt on the default cube using any brush
  5. Render. The cube disappears

On complex meshes Blender sometimes crashes when using Workbench engine and sculpt mode

I came across this assert that seems to be of high priority:
