Когда я запускаю эту программу, я получаю ошибку значения только для определенного пути. Ты знаешь, что с ним происходит?

Вот ошибка, которую я получаю при запуске программы:

 playtrack_csv_path = fix_path(config["C:\Users\user\PycharmProjects\play_track.csv"], is_dir=False)  KeyError: 'C:\Users\user\PycharmProjects\play_track.csv'
