The method text_to_numeric_binary_blocks,this padding might not be correctly handled during decryption.
The ljust method pads with zeros,which can alter the actual value of the data when converted back.
Try this.

def text_to_numeric_binary_blocks(self, text, block_size=10):
    text = text.encode()
    binary_blocks = [
        ''.join(format(byte, '08b') for byte in text[i:i + block_size])
        for i in range(0, len(text), block_size)
    ]
    return binary_blocks
