PyCharm is broken and doesn't see the library?

Question

Python

Hello!
PyCharm does not see the turtle standard library - a turtle for learning python. (OS Linux Mint)
On another computer (Ubuntu/PyCharm) the code works without errors.
On the same run in Spyder and through the terminal: python3 1.py - works .
It was PyCharm installed from the application manager that was broken.
If you remove PyCharm installed from the application manager and install from the JetBrains website, then the code also works.
I also noticed that PyCharm with JetBrains works with python3.5 (as in the system), and PyCharm from the application manager with python3.9.

What I tried:
- select the system interpreter: /usr/bin/python3 (for some reason, the 3.9 version also appears at the specified address)
- reinstall PyCharm from application manager
- reset File > Manage IDE Settings > Restore Default Settings
Nothing helps

Code

import turtle

turtle.shape('turtle')
turtle.forward(50)
turtle.left(90)
turtle.forward(50)
turtle.left(90)
turtle.forward(50)
turtle.right(90)
turtle.forward(50)
turtle.right(90)
turtle.forward(50)

Please help me figure out what is the reason for such capricious behavior of PyCharm
