user_playlist_create won't create playlist despite the correct parameters being passed through

[JoshPauls94]

This code was working fine all day for me, then I went for lunch and came back to create a new playlist and now it wont work.
Please help

It keeps running this line of code for half an hour, by which point I interrupt the process
playlist = sp.user_playlist_create(USERNAME, playlist_name, public=False, description=playlist_description)

Entire code is below

import spotipy
from spotipy.oauth2 import SpotifyOAuth
import pandas as pd

df_sorted_2 = pd.read_csv('/Documents/coding_projects/partoo/new_radio_round_up.csv')

Spotify API credentials

CLIENT_ID = client_id
CLIENT_SECRET = client_secret
REDIRECT_URI = 'http://localhost:3000'
USERNAME = username

Set up Spotify authentication

sp = spotipy.Spotify(auth_manager=SpotifyOAuth(client_id=CLIENT_ID,
client_secret=CLIENT_SECRET,
redirect_uri=REDIRECT_URI,
scope='playlist-modify-private'))

Create a new playlist

playlist_name = '4th Do You!! Roundup 2023'
playlist_description = 'Charlie Bones web scrape'
print("Creating playlist.....")
playlist = sp.user_playlist_create(USERNAME, playlist_name, public=False, description=playlist_description)
print("Playlist has been created")

Search for each song in the CSV and add it to the playlist

for index, row in df_sorted_2.iterrows():
track_name = row['Track Title']
artist_name = row['Artist']
# Use the Spotify API to search for the track
try:
# Refine the search query by including the artist name
search_query = f'{track_name} artist:{artist_name}'

    # Use the Spotify API to search for the track
    results = sp.search(q=search_query, type='track', limit=1)
    if results['tracks']['items']:
        track_uri = results['tracks']['items'][0]['uri']
        # Add the track to the playlist
        sp.playlist_add_items(playlist['id'], [track_uri])
    else:
        print(f"Track not found: {track_name} by {artist_name}")
except spotipy.SpotifyException as e:
    print(f"Error searching for {track_name} by {artist_name}: {e}")
    # Continue to the next iteration of the loop if there's an error
    continue

print(f"Playlist '{playlist_name}' created successfully.")
