I had the same problem. It is because Werkzeug 3.0.0 was released and Flask doesn't specify the dependency correctly (requirements say Werkzeug>=2.2.0). This is why, Werkzeug 3.0.0 is still installed and Flask 2.2.2 isn't made for Werkzeug 3.0.0.

Solution: Replace werkzeug==2.2.2 with previous version in your requirements.txt And again try to install all modules using pip install -r requirements.txt. Run your web app using python main.py. I hope this will work for you as well. https://werkzeug.palletsprojects.com/en/3.0.x/changes/#version-3-0-0
