Deadlock model import crashes blender

[ranidspace]

On Linux Blender 4.5.0, tested as well with latest RC for 4.5.3. I'm on the latest git version of the addon, marked as 5.5.0. I extracted the models/heroes_wip/doorman_v2/ folder as-is using Source 2 Viewer version 14.1.4764, and imported doorman.vmdl_c. There's a lot longer of a console output, but it ends with

[DEBUG]--[ContentManager:find_file]: Requesting models/heroes_wip/doorman/materials/doorman_door.vmat_c file
ERROR:root:Failed to load material models/heroes_wip/doorman/materials/doorman_door.vmat for doorman!

[DEBUG]--[ContentManager:find_file]: Requesting models/heroes_wip/doorman/materials/doorman_gundoor_portal.vmat_c file

Writing: /tmp/blender.crash.txt
zsh: segmentation fault (core dumped)  /usr/local/blender

If I extract models/heroes_wip/doorman/ to the same folder, the same crash occurs at the same point, but without the errors in the log, meaning that doesnt seem to be the issue.

The /tmp/blender.crash.txt has this:

As a test, I imported a model from CS2 with no issues using the same setup.

Unfortunately I have no idea what causing this. In blender 3.6 this model does not crash. Also, current deadlock models have a very-very weird geometry, where they have hundreds of 0-area triangles, this may be breaking modern blender versions.

I too encountered a similar crash with blender 4.5., installing a prior version (Blender 4.2) allowed me to open the Deadlock model without issue.

Should be fixed now, found a workaround;
