How to Display Warnings on OLED Based on Object Distance Using BeagleBone Black?

Hey guys, still based on my project parking assistance system using a BeagleBone Black running Embedded Linux, VL53L0X time of flight distance sensor to detect the distance to nearby objects and a 0.96-inch OLED display to show the distance and warning messages. how can I display warning messages on the OLED screen when the detected object is too close or too far. i am getting the error Error: Display not updating i have verified timing of the time.sleep() function, ensured proper buffer clearing with disp.clear() but still getting same error. here's my code

import board
import busio
import adafruit_vl53l0x
from Adafruit_SSD1306 import SSD1306_128_64
import time

# Initialize I2C bus and devices
i2c = busio.I2C(board.SCL, board.SDA)
vl53 = adafruit_vl53l0x.VL53L0X(i2c)
disp = SSD1306_128_64(rst=None)
disp.begin()
disp.clear()
disp.display()

while True:
    distance = vl53.range
    print(f"Distance: {distance} mm")

    disp.clear()
    if distance < 100:
        disp.text("Warning: Too Close!", 0, 0, 1)
    elif distance > 2000:
        disp.text("Warning: Too Far!", 0, 0, 1)
    else:
        disp.text(f"Distance: {distance} mm", 0, 0, 1)
    disp.display()

    time.sleep(1)

import board
import busio
import adafruit_vl53l0x
from Adafruit_SSD1306 import SSD1306_128_64
import time

# Initialize I2C bus and devices
i2c = busio.I2C(board.SCL, board.SDA)
vl53 = adafruit_vl53l0x.VL53L0X(i2c)
disp = SSD1306_128_64(rst=None)
disp.begin()
disp.clear()
disp.display()

while True:
    distance = vl53.range
    print(f"Distance: {distance} mm")

    disp.clear()
    if distance < 100:
        disp.text("Warning: Too Close!", 0, 0, 1)
    elif distance > 2000:
        disp.text("Warning: Too Far!", 0, 0, 1)
    else:
        disp.text(f"Distance: {distance} mm", 0, 0, 1)
    disp.display()

    time.sleep(1)
