...quoting the contents of `/home/rafal/test/tmp_folder/154_IDX_0_RAND_100719810512166459037745.py`, the rule codes D202, along with the `pyproject.toml` settings and executed command, we'd be very appreciative!

It's the line continuation character which is creating this issue. There are 2 visible newlines but the first one is escaped so there's actually only 1 which gets removed. So, the token stream would produce a string and then directly the if token which is an invalid syntax.
