Description

System Information
Operating system: Windows-10-10.0.16299-SP0 64 Bits
Graphics card: GeForce GT 720M/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 391.35

Blender Version
Broken: version: 2.91.0 Alpha, branch: master, commit date: 2020-08-22 22:24, hash: rB010c1370aff6
Worked: version: 2.90.0 Beta, commit date: 2020-08-21 15:35, hash: rBebf10b72b05f

Short description of error
Please bear with me explaining this as I already did many possible steps/conditions that can reproduce the crash.

Blender crashes IF:

  1. There are 1 or 2 scenes, and 2 view layers in any one scene, switching to other scene (either from scene drop down list or clicking other scene from Outliner) OR choosing any button from the add New Scene options (from top bar) (screenshot)

BUT it doesn't crash if I switch to another view layer first, then switch to another scene.

  1. There are 2 scenes, and only 1 view layer in each scene, it crashes if I choose any option of the add New Scene button (screenshot) OR copying current Scene then pasting it, then switch to other scene.

BUT it doesn't crash if I : A) switch to another scene; B) delete current scene; C) switch to another scene first BEFORE adding New Scene (copy paste or topbar button)

  1. There are 3 or more scenes, and 1 view layer each, it crashes either by switching to another scene OR adding new Scene (from top bar) OR copy-pasting a Scene (from Outliner) then switching to another Scene.

Exact steps for others to reproduce the error
I created 3 simple .blend files for each case:

1---2scenes-2viewlayers-on1stscene.blend588 KBDownload

  1. There is 1 or 2 scenes, and 2 view layers in any one scene: A) Switch to another scene > crash; B) Delete current Scene (from topbar) > crash; C) Add New Scene (topbar) > choose any option from the pop-up > crash.

2---2scenes-1viewlayer-each.blend585 KBDownload

  1. There are 2 scenes, 1 view layer each: A) Add New Scene (from top bar)> choose any option from the pop up > crash; B) Copy-Paste current Scene > switch to another Scene > crash;

3---3scenes-1viewlayer-each.blend594 KBDownload

  1. There are 3 scenes: A) Switch to another scene > crash; B) Add New Scene (from top bar)> choose any option from the pop up > crash; C) Delete current Scene (from topbar) > crash; D) Copy-Paste current Scene > switch to another Scene > crash.

I don't know if this is only in Windows or only with specific machine/drivers, so I also attach my system info, generated with all addons disabled because I can reproduce them without any addon enabled.

Thanks in advance for all people's hard work!
