Worked: 2.82a

Short description of error
Adding a Screw modifier to a mesh leads to immediate crash. So does opening a file containing a mesh with a Screw modifier.

Exact steps for others to reproduce the error
Add Screw modifier to default cube.
OR
Open attached file screw_cube.blend

Blender Version: 2.83 Alpha, b555b8dedc, 2020-03-30 22:07
OS: macoS 10.13.6

Confirmed on macOS, the same crash to try add a Screw modiifer to an object.
