Can not convert mesh to B Rep or Solid or Move it and the Mesh has been decimated already

[ty.brown-field]

I paid a company to create a 3D model of a character. They gave me this STL file which I am unable to do anything with in fusion 360. It won't let me move the mesh body, or use the convert mesh option or do absolutely anything with it. The original file was sent to me with over a million face groups and I used Meshmixer another program to decimate it to 9990 and I still am unable to work with it within fusion. I will link the file hope I am just missing something obvious.
