Trying to use Neopixel and DHT11 together but it fails

Hello,

I am using Raspberry Pi Pico with your libraries. When I try to put the examples together, it stucks exactly at "data = self._sm.get()" line which is under dht.measure(). Do you know why and is there any solution?

You can see my code below and I am using NeoPixel on GP6, DHT11 on GP11.

import time
from dht import DHT11
from ws2812_driver import NeoPixel


RED = (255, 0, 0)
YELLOW = (255, 150, 0)
GREEN = (0, 255, 0)
CYAN = (0, 255, 255)
BLUE = (0, 0, 255)
PURPLE = (180, 0, 255)
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
COLORS = (RED, YELLOW, GREEN, CYAN, BLUE, PURPLE, WHITE, BLACK)


dht_sensor = DHT11(11)

neo = NeoPixel(6, n=1, brightness=0.3, autowrite=False)
    
    
while True:

    # fill
    for color in COLORS:       
        neo.fill(color)
        neo.show()
        time.sleep(0.25)

    # chase
    for color in COLORS:       
        for i in range(neo.n):
            neo[i] = color
            neo.show()
            time.sleep(0.025)

    # rainbow
    for i in range(255):
        neo.rainbow_cycle(i)
        neo.show()
        time.sleep(0.0025)
    print('Here2')
    # rotate
    for _ in range(neo.n * 3):
        neo.rotate(clockwise=True)
        neo.show()
        time.sleep(0.05)
    print('Here3')
    neo.clear()
    neo.show()
    print('Here4')
    
    dht_sensor.measure()
    print('Humidity = {}%, temperature = {}C, checksum passed = {}'.format(
        dht_sensor.humidity(),
        dht_sensor.temperature(),
        dht_sensor.successful()
    ))
    time.sleep(2)
