Can someone tell me what I am doing wrong?

Thank you.

note that pyintsaller does not officially support 3.8 yet
however google-ing the error show multiple possible causes. For example - if the python was installed from windows app store, installing from python.org solves the problem for them.
So how did you install the python?

[iNickster]

I installed Python 3.8.5 from Python.org

I installed Python 3.8.5 from Python.org

That's not the version you use now.

PythonSoftwareFoundation.Python.3.8_3.8.1729.0_x64__qbz5n2kfra8p0

This is the version from windows app store.
Look at Python 3.8 (3.6-3.7) and pip installation under Windows.
Under Fixing Path if needed and point to the version from Python.org.
Restart Pc and install Pyinstaller to this version and test again.
Pyinstaller now work fine for Python 3.8,have tested it several times.
