Go to your list databases ../web/database/manager and delete the database created.

Install the package qrcode sudo pip install qrcode

Create again your database in ../web/database/manager

This work for me, I hope it helps you

For me the solution for this is go in the .../odoo/odoo/addons/base/models/ir_http.py and in this file adding the following script:

@api.model
def get_frontend_session_info(self):
     return {
         "is_admin": self.env.user._is_admin(),
         "is_system": self.env.user._is_system(),
         "is_website_user": self.env.user._is_public(),
         "user_id": self.env.user.id,
         "is_frontend": True,
     }
