I have tried running it as an admin in command prompt to no avail. Does anyone know a fix for this?

Python 3.8.x is not officially supported yet, you can try to use the dev branch or use python 3.7.x or older.

Pyhon 3.8 support still needs to be funded, see <https://github.com/pyinstaller/pyinstaller/issues/4311>

I've run into that error a number of times, but it always seems to happen when I'm running through the "git bash shell" rather than the system command prompt. Using a standard command prompt (not running as administrator) generally seems to work for me. Also, PyInstaller works fine with Python 3.8 in my experience.

I had this issue as well. For me it was because I originally downloaded Python 3.8 through the Windows App Store instead of Python.org's website. The issue is the WindowsApps folder, and even when you set permissions when it is running the script it still did not seem to allow access. I had to uninstall Python, and then reinstall from Python.org and re-set up my Python environment.

Also -- once I did this you need to disable App Execution Aliases. You can do this by searching in the Windows Task Bar. It should be disabled for "App Installer python.exe" and "App Installer python3.exe".

After this, it should solve your issue -- at least it did for me. I was stumped for a very long time.
