I tried uninstalling and then installing Werkzeug and Flask, but the same error is still happening.

Thanks for the report. Looks like installing werkzeug<2 should work. Wonder why no one reported this before.

Hey!, by the way. I looked into your profile. Futurecoder looks like a great project, and its a great vision you have. I think this kind of work should have more visibility. My respects.

Thanks, please share it with all your friends!

The fix for this bug has been released to PyPI.
