rpi-hardware-pwm not working on RPi5

[niekas7]

Just installed a fresh new raspbian OS and set up rpi-hardware-pwm. Python version is 3.11.2. Previously before updates the my code was doing just fine. Everything worked as expected. But now that I updated it the pwm_bcm2835 doesnt show up and if I run my code it gives me an error.

from rpi_hardware_pwm import HardwarePWM
import time

# Initialize the PWM channel on chip  2, channel  1, with a frequency of  50Hz
servo = HardwarePWM(pwm_channel=0, hz=50, chip=2)

def angleToSteps(angle):
    # This function converts an angle to a duty cycle.
    # You might need to adjust the formula based on your specific servo's requirements.
    # The original code uses a correction factor of  0.88, but this might need to be adjusted for your setup.
    correctionFactor =  0.9
    dutycycle =  2.4 + (angle /  18) * correctionFactor
    print(f"angle={angle}, dutycycle={dutycycle}")
    return dutycycle

def moveServo(angle, sleepVal):
    # Change the duty cycle to move the servo to the specified angle
    servo.change_duty_cycle(angleToSteps(angle))
    time.sleep(sleepVal)  # Wait for the servo to move
    servo.change_duty_cycle(0)  # Reset the duty cycle to stop the servo


try:
    servo.start(0.0)
    moveServo(0.0, 1.5)

    isTestAngleInput = True
    isTestAngleRange = False #False

    while isTestAngleInput:
        angle = float(input('Enter angle between  0 &  180 (enter angle<0 to exit): '))
        if angle<0:
            break
        moveServo(angle, 1.5)
        #time.sleep(1)  # Wait for a second before asking for the next angle
    if isTestAngleRange:
        for x in range(180):
            moveServo(x, 0.1)

finally:
    servo.stop()  # Stop the PWM signal
    print("Servo Stop")

The error I get is

During handling of the above exception, another exception occurred:
