Cannot run program "/../../python.exe" (in directory "/PythonSoftwareFoundation.Python.3.8_3.8.240.0_x64__qbz5n2kfra8p0"):Access is denied
Try installing Python 3 from the actual Python Webpage. 
The windows store version may be confusing pycharm by storing/sorting the .py files in an odd way. Could also be a PATH issue due to windows store version etc.
Hope this helps!
I'm getting this error anytime when creating a new project in pycharm:

Cannot run program "C:\Program
  Files\WindowsApps\PythonSoftwareFoundation.Python.3.8_3.8.240.0_x64__qbz5n2kfra8p0\python.exe"
  (in directory "C:\Program
  Files\WindowsApps\PythonSoftwareFoundation.Python.3.8_3.8.240.0_x64__qbz5n2kfra8p0"):
  CreateProcess error=5, Access is denied

I have Python 3.8 installed from Windows Store but when I try to create the project it says "Choose another SDK"
It seems like a fairly common issue but since I'm new to Python I'm not really sure what it involves.
