Command Prompt Gets Stuck Upon Running PyFirmata Function

Question

I'm trying to run some Python to control a servo on my Arduino. About a week ago, I got it all working, and there were no issues. Now, when I run the same code (code below) my computer gets stuck in the rotate function. Im using the module PyFirmata2, though I have tried it with PyFirmata. Im using a really old version of Python (3.9.9) because PyFirmata leaves something to be desired.

This is the python, it's saved in a note (MCT3.py) which is then run. I have verified all the ports and pins are correct.

from pyfirmata2 import Arduino ,SERVO,util
from time import sleep

port = 'COM4'
pin = 10
board = Arduino(port)

board.digital[pin].mode = SERVO

def rotate(pin, angle):
    board.digital[pin].write(angle)
    sleep(1000)

print('START')
x = str(input('Angle: '))
rotate(pin, x)
print('DONE')

This is my steps and the output:

C:\Users\bguyl>python MCT3.py
START
Angle: 90

I can let it sit as long as it wants and it won't print "DONE". It does, however, rotate the servo to the correct angle, it just won't continue the code afterward.

This is a problem because I need this in a while loop eventually and if it cant get past the rotate function I wont be able to enter multiple angles in a row.

This might be a really easy fix, but I don't use windows that much :)
