System Information
Operating system: Windows-10-10.0.19045-SP0 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 436.50

Blender Version
Broken: version: 3.4.0 Alpha, branch: master, commit date: 2022-09-09 00:25, hash: 81558783e4
Worked: version: 3.4.0 Alpha, branch: arcpatch-D15914, commit date: 2022-09-08 15:28, hash: 4d08eb16d0

Caused by 05952aa94d

Simplified short description of error
Blender crashes if try to call Fix Deforms operator if Vertex Selection is enable and no one selected vertex haven't weight of selected bone.

Short description of error
Blender crash in weight paint mode and vertex select is clicked and then you click on Weights -> Fix Deforms.

Exact steps for others to reproduce the error

EDIT: simplified with demo file

Open the file
Click on Weights->Fix Deform

Full instructions

Start blender and load factory settings.
Toggle x-ray mode. (Makes it simpler to see)
Select default cube and tab into edit mode.
Make a horisontal loop cut.
Tab out of edit mode.
Add Armature -> Single bone.
Move the bone down 1. g + z - 1
With the armature selected, tab into edit mode.
Extrude the tip up 1. e + z + 1
Change viewport display for the armature to be "In Front". (Makes it simpler to see)
Select default cube and shift select the armature.
Ctrl+P -> Set Parent To -> Armature Deform With Automatic Weights
Select armature and shift select default cube.
Go into Weight Paint mode.
Select the top bone.
Click on Vertex Select. Make sure some vertexes are selected.
Click on Weights -> Fix Deforms
Blender crashes.

This looks a lot like #69004 Weight Paint - Fix Deform crash . Except the last step "Adjust the options at the bottom of viewport" is not needed.

Debug logs. There's an error in what the blender_system_info.txt shows. If I enable an add-on. like rigify, then click on File ->Defaults -> Load Factory Settings. Then click on Preferences -> Add-ons and search for rigify I see it's not enabled. But blender_system_info.txt shows it as an enabled add-on.

Also "Load Factory Settings" doesn't load blender as when downloaded, which I thought. It' seen in step 6. If I disable rigify there's no option "Single bone" when adding an armature. But if it's enabled and then loading factory settings "single bone" is still there. I have manually disabled rigify and other add-ons but the crash is still happens.
