Can't print out a list of files in a folder using os.listdir ("...") error Python [duplicate]

I'm trying to get a list of all the files in this folder then print them but I keep getting an error (using python).

import os

files = os.listdir("C:\Users\Alex\Desktop\Channel")

Error - File "C:\Users\Alex\PycharmProjects\First\venv\First.py", line 2files = os.listdir("C:\Users\Alex\Desktop\Channel")^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape.

I moved the folder around and changed its name many times but nothing seems to work.
