The enter key sometimes doesn't work

The enter key sometimes doesn't work.
I used the code below to get the program to press enter

Codes

# -*- coding: utf-8 -*-

try:
    import pydirectinput as pdt
    import time
except:
    from pip import main
    main(['install', 'PyDirectInput'])
    import pydirectinput as pdt
    import time

pdt.FAILSAFE = False
pdt.PAUSE = 0.05

T = 't'
ENTER = 'enter'
sleep = 2
command = '/sell string'

time.sleep(sleep)
loop = 0
while True:
    
    loop += 1
    print(loop)
    print('Start')
    pdt.press(T)
    print(T)
    time.sleep(0.001)
    for i in command:
        pdt.press(i)
        print(i)
        time.sleep(0.001)
    pdt.press(ENTER)
    print(ENTER)
    print('End')
