System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3090/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 537.42

Blender Version
Broken: version: 4.0.0 Beta, branch: blender-v4.0-release, commit date: 2023-10-03 09:39, hash: a06403cd3b9c
Worked: 3.6.4 stable LTS

Short description of error
Node groups with virtual input sockets, converted from earlier versions or created programmatically I suppose, prevents loading blend file in Blender 4.0 and above (tested 4.1 alpha as well).

Exact steps for others to reproduce the error
The provided crash.blend file contains a minimal example that works in Blender 3.6.4, but fails to load in Blender 4.0 and up. The virtual sockets have been created by an addon named scattershot since I don't know how to create them through the UI. Stack trace is shown below.
