The error is somewhat misrepresented, telling it to delete a field that doesn't exist(or may have existed before) but shouldn't be the cause of the error when making migrations.

Migrations for 'post': post/migrations/0022_auto_20200929_1749.py - Remove field category from post - Remove field tag from post Traceback

If I am correct, you may be using Django 3.1, which moved the BASE_DIR pseudo-setting to use pathlib.Path rather than a plain string. Support for this needed adding str() to some places like the sqlite driver.

If you look at the definition of BASE_DIR in your settings file, is it using a Path() ? If so you can use str() around its use in your DATABASES setting, i.e. str(BASE_DIR / "something.sqlite").
