OSError: [Errno 5] EIO : When using 2 of the same sensors with same address on different I2C channels

I'm using a Cytron Maker Pi RP2040 Micropython

The sensors are VL53L1X from Adafruit

Sensor0 is connected to (SDA1)-GPIO26, (SCL1)-GPIO27 Sensor1 is connected to (SDA0)-GPIO16, (SCL0)-GPIO17

I found this in Github and I'm using the same library as them. The library in question

I am fairly new to this but I've managed to make one of the sensor work at a time. But whenever I try to use 2 the second one gives me OSError: [Errno 5] EIO I made sure both are in different channels.

enter image description here

This is my set of funtions

class distance:

    def true_front(channel):
        global front_distance
        i2c = I2C(channel)
        distance = VL53L1X(i2c)
        front_distance = distance.read()
        print(str(front_distance) + "mm")
        sleep_ms(50)

    def true_rear(channel):
        global rear_distance
        i2c = I2C(channel)
        distance = VL53L1X(i2c)
        rear_distance = distance.read()
        print(str(rear_distance) + "mm")
        sleep_ms(50)

And this is how I executed them

while True:
    distance.true_front(0)
    sleep(1)
    distance.true_rear(1)

I looked into the library to see if there was a way to redo the handshake process everytime I call the funtions, but since this is still new to me I didn't manage to spot the solution.
