MacBook Air MacOS Mojava (10.14.6) crashes when python turtle module is executed using python 3.8.5

from turtle import Turtle

laura = Turtle()

laura.color('red')

laura.shape('turtle')

When I execute the code above, a small python launcher appears and then, my MacBook either restarts, freezes until I restart it using the power button or displays a white screen with black lines (static screen) before restarting. I use IDLE to type up the code, however when I run it using python launcher, it crashes as soon as laura = Turtle() is executed. However on another admin on the same MacBook, it does not crash or restart but works successfully.

Please advice me on how to fix this issue.

Thank you.
