The "ImportError: cannot import name 'json' from 'itsdangerous'" error occurs due to incompatibility between Flask and itsdangerous package

. The json module has been removed from the itsdangerous package, which causes this error

. To fix this error, you can upgrade your version of Flask to version 2 or higher, which uses the TimedJSONWebSignatureSerializer method from itsdangerous instead of json

. Alternatively, you can downgrade your version of itsdangerous to version 2.0.1

pip uninstall itsdangerous
pip install itsdangerous==2.0.1
