System Information
Operating system: Windows 11 Home
Graphics card: RTX 3050 mobile gpu

Blender Version
Broken: 4,0 beta, blender-4.0.0-beta+v40.4d3534401060-windows.amd64-release
Worked: 3.6.x (and earlier - used import those .dae files since 2.9)

Short description of error
importing .dae file causes immediate crash of blender if the .dae file has armature (which probably has something to do with vertex groups)

Exact steps for others to reproduce the error

Run new blender instance
click -> file -> import -> collada (.dae)
import test_with_armature.dae file
blender crashes

if you choose the other one it won't crash. those file are exports of makehuman app.

Can confirm, crash is because ExtraTags *et = getExtraTags(node->getUniqueId()); is null, and is used in bc_add_armature
