What happened?

import turtle as ttl

ttl.shape('turtle')
ttl.speed(0)

# draw a line
ttl.forward(200)

ttl.mainloop()
print('done')

If you run it twice, it will report an error. The third time, it can run normally again. Unless you kill the kernel, an error will occur every time you run it repeatedly.

It might just have some trouble with initialization and teardown of the external app. Looks like @DonJayamanne has done some previous work to get turtle working on #8241

@ydmykr
Can you run the same code in Jupyter Notebook (outside VS Code) and let me know if you run into the same problem

[ydmykr]

Unfortunately, I will still encounter the same problem.

Thanks for getting back to us, Looks like a problem with the package itself, or other.
Unfortunately I'm not an expert of the turtle widget, please react out to the maintainers of the turtle package for assistance.
Closing this issue as this isn't a problem with the Jupyter extension.
