python - Flask app Heroku Error App Crashed Windows

Question

Im trying to deploy my flask app on heroku for the first time and running into some errors: Here's the log for the application

i havent really installed gunicorn on my windows OS and just followed this tutorial on youtube: https://www.youtube.com/watch?v=h43s0nHV_20

My Procfile contains:

web: gunicorn app:app

My requirements.txt contains:

nltk==3.5
Flask==1.1.2
numpy==1.19.2
Keras==2.4.3

How can I solve this issue? Also from what I know gunicorn is installable on linux only so is there a way around that?

After adding gunicorn in requirements.txt:
