Short description of error
When workspace consists of a 3D View and UV Editor, hiding all UVs while sync selection is on causes Blender to crash.

Exact steps for others to reproduce the error

  1. Split workspace into UV Editor and 3D View
  2. With UV Editor focused, Tab into Edit Mode so that the UV shows
  3. Enable sync selection
  4. Start hiding UV fragments
  5. Observe crash when last UV fragment is hidden

Doesn't crash if sync selection is off or when no 3D view editor is open. See attached gif and example blend file.
