Hi, I just subscribed to Odoo after trying out the free trial. When I did the trial it was still Odoo 15 version and I had no problem configuring things the way I wanted. However, when trying to customize in Odoo 16 I had come across these errors when adding new fields:

- When I click "Edit List View" or "Edit Form View":

UncaughtPromiseError > OwlError

Uncaught Promise > The following error occurred in onWillStart: "View is not a constructor"

- When adding many2one, one2many, many2many fields:

UncaughtPromiseError > TypeError
Uncaught Promise > ViewClass is not a constructor

Any help will be much appreciated! :)
