This error occurs when the Python interpreter encounters a string with a Unicode escape sequence that is not correctly formatted. The escape sequence in question is indicated by the \U and the X's that follow it, and it is used to represent a Unicode character using its hexadecimal code point.
The error message indicates that the escape sequence is truncated, which means that it is missing one or more digits that are necessary to represent the full code point. This can happen if a backslash is used in the string for some other purpose, such as to represent a file path or a regular expression, and the backslash is interpreted as the start of a Unicode escape sequence.
To fix this error, you can either double up the backslashes in the string to escape them, or use the 'r' prefix before the string to indicate that it is a raw string and should not interpret backslashes as escape sequences. For example:
```
# Double up backslashes
my_string = "C:\\Users\\myuser\\Documents\\file.txt"
# Use raw string
my_string = r"C:\Users\myuser\Documents\file.txt"
```
