Track Studio refuses to open FBX file because of internal error?

[CelesteMeowMeow]

Whenever I'm trying to open up an FBX file it gives me this error.

An item with the same key has already been added. Key: Texture::base_color_texture

Update - Killz is looking into using the "assimp" library for FBX models instead of the existing one, which should hopefully work better.
FBX import errors are a known issue due to the importer only working with older models, and so it is recommended to use .dae files for the time being (until FBX is fixed or GLTF/GLB import is no longer a WIP)
