Description

Windows 10 x64 Operating System
Error in Version "blender-2.90.0-1d4bae856690-windows64"

In Blender version 2.83.0 Beta and Blender 2.90.0 Alpha these unexpected closings happen with the following procedures that do NOT happen in Blender version 2.82.7:

1- We create a Cube or a sphere.
2- We create an Area Light.
3- We go to "Shading" and put in the view "Shading of the view".
4- In the processing engine we place it in "CYCLES".
5- We enter the Light properties (Object data properties) and click on "AREA".
5- We mark the option "Portal" and there is automatically the program closes completely and loses some information if it has not been saved.

@Brecht Van Lommel (brecht) I would suggest revert 33ce0cb5a1ed and try to fix T63588 again in master.
