Exact steps for others to reproduce the error

Add a new Empty GP to a new project
Add a new GP layer and enable "Autolock Inactive Layers"
Switch to Draw mode and draw anything
Switch to Edit mode and Select All/anything
In the Material Properties, add a new Material slot. Select a new Material (e.g. default Dots Stroke)
Press Assign: the new material is assigned to the stroke
Undo/Ctrl+Z crashes Blender

If Autolock is disabled, it works. On 4.2.0, any combination works.
