same with me

I am also facing same error

I had the same issue using a List of files generated by the pathlib module:
List_of_matching_Files = Path(parent_directory_path).glob(pattern_to_match_in_filename)
(This may also occur other glob() functions.)
The List_of_matching_Files is a List is of some sort of custom Type, that looks like a string, but really isn't.
The following correctly maps each filename to a string, then you can use the string with imread, imwrite, etc.
List_of_matching_Files = list(map(str,List_of_matching_Files)
