I get a 'specific module could not be found' error? Help?

I had the same issue - due to missing a dependency for fbgemm.dll. Solution I used was to install updated MS VC++ redistributable.
Go to https://visualstudio.microsoft.com/visual-cpp-build-tools/, then Download Build Tools.
Run it, go to Individual components tab, find MSVC v143 -VS 2022 C++ x64/x86 Build tools (latest) and install.
