Streamlit unable to open files in project directory

Yesterday I built a Streamlit project that uses .dat and .xml files to detect faces and facial landmarks. It was working perfectly the day I built it, but today it cannot find the .xml and .dat files. They are located in the same folder as my project is on my machine. When I check to see if they exist using: os.access(‘shape_predictor_68_face_landmarks.dat’, os.F_OK), it returns false, although I see them in the folder.
I found the following solution on these forums but it did not work:
predictor = Path(file).parents[0] / ‘shape_predictor_68_face_landmarks.dat’
dlib_facelandmark = dlib.shape_predictor(predictor)
This is the exact error I am receiving:
File “C:\Users\hanna\PycharmProjects\FaceDetector\”, line 87, in detect_faces
dlib_facelandmark = dlib.shape_predictor(‘shape_predictor_68_face_landmarks.dat’)
RuntimeError: Unable to open shape_predictor_68_face_landmarks.dat
