When I run py -3 -m venv venv on command prompt to create a virtual environment it fails.
"Error: Command '['C:\\Users\\Guest\\Desktop\\Python Web
App\\venv\\Scripts\\python.exe', '-Im', 'ensurepip', '--upgrade', '--default-
pip']' returned non-zero exit status 101.
How to fix this? I've installed the latest Python Version. I'm stuck here on my way to set up Flask for web development.

To use the virtual environment you created to run Python scripts, simply invoke Python from the command line in the context where you activated it. For instance, to run a script, just run python myscript.py .
If you try to run virtualenv and find it isn't present, you can install it using pip. virtualenv.exe will likely now be found in your python installation directory under the Scripts subdirectory.
You can exit from the virtualenv using exit command, or by pressing Ctrl+d.
These are almost completely interchangeable, the difference being that virtualenv supports older python versions and has a few more minor unique features, while venv is in the standard library.
This happened after I upgraded from python3.8 to python3.9.
sudo apt install python3.9-venv
should solve the issue

I had this problem - the workaround was to uninstall Python and reinstall it with the Install for all users option. See my longer answer: https://stackoverflow.com/a/62207756/11308690

I tried reinstalling python to no avail. This problem seems to occur when copying the python executable doesn't work (fully) for whatever reason (seems to be related to PyCharm). I recreated my venv with the --clear --symlinks:
python -m venv --clear --symlinks ./venv
