Pycharm unable to debug the Python Flask project

I have a simple Flask based project in Pycharm. I am trying to debug this by right clicking and selecting debug option. But keeps getting below error:

Connected to pydev debugger (build 232.9559.58)
 * Serving Flask app 'app'
 * Debug mode: on
WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead.

 * Running on
 * Running on
Press CTRL+C to quit
 * Restarting with stat
C:\Python311\python.exe: can't open file 'C:\\Program': [Errno 2] No such file or directory

Process finished with exit code 2

I am unable to understand why and what it is looking for in 'C:\\Program'. I am able to run the file perfectly fine and only having issues in debug. What can I try next?


  • This appears to be a bug in Pycharm. Multiple issues have been raised for the same in the JetBrains bug tracker.
