Short description of error
I imported an animated FBX model generated via Mixamo. 3D model is ok.
I try to export to an glTF file and the system doesn't save to the specfied location.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
