No 'Access-Control-Allowed-Origin' headers even though django-cors-headers is, how can I fix this?

Question

Django

Good evening to everyone who watches this, the problem is this, there used to be KORS, now (after adding new functions to views, but not touching settings at all), he writes that it is not there (in the application), tried to add it manually failed.

The question is, how can I restore KORS in the application?

django==2.2
django-cors-headers==2.2
python==3.5.3
