When it you get "can't reload" of a .so object, then there are a small number of possibilities:
  • the so object no longer exists; or
  • the so object is no longer accessible, because permissions have changed; or
  • the so object is not currently accessible, such as if it lives on a network drive that cannot be reached; or
  • you ran out of memory

I see some claims that missing libraries or missing fonts can cause the problem; see https://www.mathworks.com/matlabcentral/answers/361053-can-t-reload-usr-local-matlab-r2017b-bin-glnxa64-libmwdastudio-so
