Makemigrations are not executed and tables are not created in the Django database

Development in Visual Studio 2017. When performing "makemigrations", as well as when checking "manage.py check" I have the same system response:

Execution is underway: manage.py makemigrations

Traceback (most recent call last):
File "...\DjangoWeb\env\lib\site-packages\django\db\backends\utils.py", line 64, in execute
    return self.cursor.execute(sql, params)

File "...\DjangoWeb\env\lib\site-packages\django\db\backends\sqlite3\base.py", line 328, in execute

return Database.Cursor.execute(self, query, params)
sqlite3.OperationalError: no such table: app_entry

The above exception was the direct cause of the following exception:

In this case, all migration files in the "migration" project folder are deleted, except for the "-- "file. init--.py", and deleted the file of the database itself and re-created by the system, but constantly gives the above error..

What could be the problem here and how is it fix it?
