CYBER ASTRONAUT-F Rigged for Unreal Engine - Unity - MIXAMO 3D model

UPDATE: The seller reached out to me and was able to help figure things out! When I try to export the model to fbx with, our without the rig, I get this error: Python: Traceback (most recent call last): File "C:\Program Files\Blender Foundation\Blender 4.2\4.2\scripts\addons_core\io_scene_fbx\export_fbx_bin.py", line 3519, in save_single fbx_objects_elements(root, scene_data) File "C:\Program Files\Blender Foundation\Blender 4.2\4.2\scripts\addons_core\io_scene_fbx\export_fbx_bin.py", line 3313, in fbx_objects_elements fbx_data_mesh_elements(objects, me_obj, scene_data, done_meshes) File "C:\Program Files\Blender Foundation\Blender 4.2\4.2\scripts\addons_core\io_scene_fbx\export_fbx_bin.py", line 1400, in fbx_data_mesh_elements raise RuntimeError("UV layer %s on %r has invalid UVs containing NaN values" % (uvlayer.name, me)) RuntimeError: UV layer UVMap on bpy.data.meshes['Cylinder.029'] has invalid UVs containing NaN values I don't have auto rig pro, which might be the problem. If so, that kinda sucks because it's a $50 plugin. The only included FBX that Blender recognizes is one labeled 'untitled' which isn't rigged and none of the textures are included. There's another one labeled ASTRONAUT but it always just ends up freezing my project in Unreal Engine, which is surprising because I have a professional grade PC that I use to run much more complicated stuff. Overall, disappointed and confused.
