SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 164-165: truncated \UXXXXXXXX escape

This error occurs when you try to include a Unicode escape sequence in a string but the sequence is not properly formatted. The \U escape sequence is used to represent a Unicode character using 8 hexadecimal digits. The error message indicates that there is a problem with the escape sequence starting at position 164-165 within the string.

To fix this error, you need to check the string and ensure that any Unicode escape sequences are properly formatted. For example, if you intended to include the Unicode character U+0041 (Latin capital letter A), you should use the escape sequence \u0041 instead of \U00000041. The former uses 4 hexadecimal digits, while the latter uses 8.
