How to fix no such table: main.auth_user__old problem?

Question

Django

Here is the error: dpaste.com/0CM2P00
It appears after trying to add any entry to the database, in any model.
However, this problem suddenly appeared yesterday, before it did not exist, and rolling back to the previous version of Django does not help.
The Python version was not updated, SQLite was not updated, nothing was updated, but the error is systemic and now on every new project.
I don’t understand what to do and where to look, while hosting has an older version of python and sqlite and the newest version of Django, but it stopped working only locally, everything is fine on the server.
PS
Neighboring projects previously created work without problems. Only those projects that I have been creating since December 17, 2018 do not work.
