VS ERROR (python) = Project cannot be launched because startup file is not specified

That is how I solved this problem;

1. Add a python empty module to project,
2. Set it as a Startup project,
3. then Run.

That's all.

I came across similar error, but googling found the detailed solution by MS at:

https://learn.microsoft.com/en-us/visualstudio/python/managing-python-projects-in-visual-studio?view=vs-2022

You can simply:

1. Right click the Solution in your Solution Explorer selecting the Startup Project to be the relevant one.
2. Then right click the said project containing the file you want to run, and click properties.
3. Finally ensure the name of the file you want run is specified in the Startup File box!
