Hi,

I'm using Odoo 14 Community Edition for a non-profit organization, with Odoo Mates accounting app.

I was trying to setup differed revenues using modules account_cutoff_base and account_invoice_start_end_dates, then I realized that I couldn't access General Settings anymore. 

Trying to reach the view gives me following error: 

Error: field_utils.format[(intermediate value)] is not a function
_formatValue@https://odoo14.legaragenumerique.fr/web/static/src/js/fields/abstract_field.js:392:65
_render@https://odoo14.legaragenumerique.fr/web/static/src/js/_deprecated/basic_fields.js:104:30
_render@https://odoo14.legaragenumerique.fr/web/static/src/js/fields/upgrade_fields.js:94:21
OdooClass.extend/

I also realized that, although Stock app is not installed on my system, I had a Stock entry in main menu, but I can't access it:

I don't know what to do to solve this, and I don't have a way to roll back my instance..
