here’s the thing, sometimes the model file will import just fine without a issue, other times it just crashes, but, it can be the exact same model file…
i.e. Import model: crash, import same model, no changes to file: it worked, next time, crash… there doesn’t seem to be any rhyme or reason to why its crashing on the model import.
Here is the dump from the latest crash:

based on the starting line of the dump, I thought it was because of the UV map layout, so I redid the UV map, exported it to a new file, same thing happens, thus far I have 3 models I’ve created that ‘sometimes’ will import, other times crashing with a similar message. Like I said, no consistancy to why its happening.
