Crashing on save with specific materials

When I try to save a file with cloud ambientcg procedural metal046a_4k.jpg I get an instant crash when saving and the file is not write. This happens with a select few other materials but this one is easy enough to replicate. If this material is applied to the mesh, even when merged with other textures it results in a crash.

This happens even when I am running in administrator mod.
I am on windows 10
Any idea why?

Okay so I played around some more with it, if I apply the materials to the default cube, then import my model and apply my materials then to my model it will save.
