Sorry, but as Ronald says there's not nearly enough information here. Some questions:

- What do you mean by "embedded Python"?
- What is "the exe" that you refer to in your second mesasge? Is that python.exe? Is that an executable you compiled from your Python code somehow? If so, how?
- What operating system are you using?
- What exact version of Python are you using, and where did you get it from? (Conda? python.org install? OS package manager? Pre-installed?)
- What other dependencies are you using? Any 3rd party packages?
- What's the exact Python code that you're running? (Please attach all the Python code, preferably after first reducing to a minimal example that exhibits the issue.)
- What are the precise steps you used to invoke the Python code? (Are you running as a script from a command-line prompt? Interactively in IDLE / PyCharm / VS Code / some other IDE?)
- What exactly happened?
- What did you expect to happen, and why?
- What steps have you taken to eliminate the possibility that this is a bug in your own code rather than in Python?
