I think it could be this:

A backslash-character pair that is not a valid escape sequence now
generates a SyntaxWarning, instead of DeprecationWarning. For example,
re.compile("\d+\.\d+") now emits a SyntaxWarning ("\d" is an invalid
escape sequence, use raw strings for regular expression:
re.compile(r"\d+\.\d+")). In a future Python version, SyntaxError will
eventually be raised, instead of SyntaxWarning. (Contributed by Victor
Stinner in gh-98401.)

It's not supposed to crash your program though. If the program crashes
because of it, it's a bug in Python.
