UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcb in position 0: invalid continuation byte

This error occurs when a program tries to decode a byte string using the UTF-8 codec, but encounters a byte that is not valid according to the UTF-8 encoding rules. In this case, the byte 0xcb is not a valid continuation byte in UTF-8.

To fix this error, you need to determine the correct encoding of the byte string and use the appropriate codec to decode it. You can try using a different codec, such as latin-1 or utf-16, to see if that resolves the issue.

Another possible solution is to ensure that the input data is properly encoded in the first place. You can try opening the file or input stream in binary mode and then decoding the bytes explicitly, rather than relying on the default decoding behavior of the program.
