This seems to be a truncated text of an error message beginning with "Nie można" - I'm guessing you're on a Windows machine with Polish set as the system language.

I've encountered this error myself after removing my Python installation that I've downloaded from the Microsoft store. In my case the solution was simple - to install Python using the most basic official package from https://python.org. I've found that on Windows this is the best way to install Python, aside from using Anaconda, which is more convenient if you work rather on data science and similar topics.
