Impacted versions: 14 community.
Windows version.

Steps to reproduce: Tried to add custom field to the sale.order view. Field was created properly in the database, but couldn't save sale.order.tree view. Error: website_id is not a proper filed in sale.order Tried to reinstall website module , but now cannot even start the Odoo insatnce. I'm not a developer, but have Pycharm and pgAdmin installed and can perform some changes and write some basic code. Any help would be appreciated
The following modules were installed correctly:

Sales, Purchase, Inventory, Manufacturing, Website

Also from OCA:

Product Secondary Unit 14.0.1.0.0

Purchase Order Secondary Unit 14.0.1.0.0

Sale Order Secondary Unit 14.0.13.0.1.0.0
