FileNotFoundError: [WinError 2] The system cannot find the file specified

Running this with Spyder in a miniconda environment on Windows. I'm not sure what file is not being found?

Ran the code on my WSL2 (Windows Subsystem for Linux) . Ran fine. Started a new conda environment on Windows. Got the same error.

I'm not sure? That could be the case, but not savvy enough to troubleshoot that.
