System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1060 6GB/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 441.41

Blender Version
Broken: version: 2.90 (sub 0), branch: master, commit date: 2020-05-01 21:55, hash: 83304e4c22
Worked: (newest version of Blender that worked as expected)

Short description of error
[Please fill out a short description of the error here]

When Load UI is off, and you click at file - new - create a new template, and then go again at file - new - create the same template, then Blender crashes.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

Open Preferences, go to Save & Load, untick Load UI.
Go to File > New > Sculpting . Now go again to File > New > Sculpting. Blender will crash to desktop. This can be repeated with the other templates too. When you call the same template twice with Load UI off then Blender crashes.

See attached video, screenshot and crash log.

Looked into #75893 and don't think it's related.
While a NULL check here looks valid (as all screen data has been cleared). The actual result of the operation does load in new screen data, so I'd like to double check that this isn't bypassing versioning that should be done.
