System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3080 Laptop GPU/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.59

Blender Version
Broken: version: 3.2.0 Alpha, branch: master, commit date: 2022-05-01 23:31, hash: a5644f9a28
Worked: (newest version of Blender that worked as expected)

Short description of error
The new hair system crashes blender if no tool is selected from the T Panel

Exact steps for others to reproduce the error

Add the Curve Random object (It is under the Experimental tab )
Withe the curve hair selected, go to the Sculpt Mode.
Left click anywhere in the view port and blender will crash.
broken hair.blend

[Based on the default startup or an attached .blend file (as simple as possible)]

I know this is an experimental tool, but still it need to not be fixed, and one easy solution is to have the 3d cursor as default selected in the T Panel.
