This is an issue with Blender itself.

So uh, the best thing I can do is wait for the update? Like, I cleaned some stuff, some other versions of Blender I had for specific addons, checked local files, but the issue remained.

When I open "Material" tab on imported .smd from Garry's Mod or "Shading" tab - program freezes and dies.
