System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: AMD Radeon R7 200 Series ATI Technologies Inc. 4.5.13596 Core Profile Context 20.5.1 27.20.1017.1011

Blender Version
Broken: version: 2.90.0, branch: master, commit date: 2020-08-31 11:26, hash: 0330d1af29
Worked: Not sure, file created with 2.83 but not tested this scenario at this moment (EDIT: working well in 2.83.5)

Short description of error
Blender crashes if you toggle the holdout option from the visibility tab in the object settings when the viewport its in rendered shading

Exact steps for others to reproduce the error

Open the attached file. Sombras Imposibles.blend
Toggle off the Holdout button in the visibility tab, from the object properties
Nothing happens....
Change the viewport to Rendered
Toggle again holdout
Blender crashes
