Operating system: Windows 10
Graphics card: Geforce 1080
Broken: v 2.81a and 2.81
Short description of error
Adding a Bevel modifier to an object leads to instant crash of Blender.
Exact steps for others to reproduce the error
I have created a window with archimesh, updated the mesh, added uv and a material. Then I removed all parenting with Alt-P, then removed the group and empty created by the addon, such that the object only contains the window.
When I now add a Bevel modifier, Blender crashes instantly.
This can be reproduced with the attached file in 2.81 and 2.81a.
