python 3 - ModuleNotFoundError: No module named 'encodings'

I just started to learn python 3 few months ago, and I having problems in the pycharm IDE... it is very annoying and i wish someone could help to fix that. when I run any code,

PRINT:

Fatal Python error: Py_Initialize: unable to load the file system codec
ModuleNotFoundError: No module named 'encodings'
