Button only works once

[Zachary-Crimmel]

So not sure what's happening but the button will only correctly run Slippi once. My thought is that the virtual environment is still running or some background process is still going but when I try to run again and test the button, I get this error
'.' is not recognized as an internal or external command,
operable program or batch file.
This can be a lower priority item as we still need JSON functionality and some fields input and passed into the JSON.
