System Information
Operating system: Windows-10-10.0.22631-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 4090/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 546.33

Blender Version
Broken: version: 4.1.0 Alpha, branch: main, commit date: 2024-01-26 02:43, hash: da77f90744c1
Worked: 4.0.3

Short description of error
As soon as an Extrude Mesh node is placed and connected, on a mesh with a vertex group, blender crashes without warnings

Exact steps for others to reproduce the error
Select the default cube, create a new vertex group, add a geometry nodes modifier, place an Extrude Mesh node and connect it.

Attached is a stripped down file where I first encountered the issue, it was saved in 4.0.3 with the Extrude node already in place, so it crashes at startup when opened with 4.1. Deleting the vertex group prevents the crash.
It was broken before i upgraded to the latest daily build, i believe the previous version i had was the daily 4.1 build from 18/01/24

this may be useful:
