We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
`plasma-calculator` does not launch on a Windows 10 system
Original comment...https://github.com/PlasmaPy/PlasmaPy/pull/1610#discussion_r912220976

The `plasma-calculator` does not launch when using a Windows 10 system...

> Also, I get an error when trying to run the calculator on my windows machine...
>

>
> My suspicion is whatever functionality is generating the file path is ignorant of a windows file separator, since the path and file name are mashed into one without a separator.
