• Searched main docs for your problem www.PySimpleGUI.org
• Looked for Demo Programs that are similar to your goal Demos.PySimpleGUI.org
• If not tkinter - looked for Demo Programs for specific port
• For non tkinter - Looked at readme for your specific port if not PySimpleGUI (Qt, WX, Remi)
• Run your program outside of your debugger (from a command line)
• Searched through Issues (open and closed) to see if already reported Issues.PySimpleGUI.org
• Tried using the PySimpleGUI.py file on GitHub. Your problem may have already been fixed but not released

Detailed Description

Noticed that upgrading PySimpleGUI to the github version had trouble when there is a Python interpreter specified in the PySimpleGUI settings. Removing the interpreter caused it towk function correctly.

Code was added a few releases back to handle this specific situation so something about that code isn't quite right.

Start at the psgupgrade command and reproduce the upgrade with a Python interpreter configured in PySimpleGUI settings, comparing it with the case where that setting is removed. Trace the code added to support a configured interpreter and verify that upgrading to the GitHub version works in both cases on the reported Windows and Python versions.
