There is many issues around this type error:
**WindowsError: [Error 123] The filename, directory name, or volume label
syntax is incorrect: '<frozen importlib._bootstrap>'**

https://stackoverflow.com/questions/57108779/how-to-solve-oserror-
winerror-123-the-filename-directory-name-or-volume-lab
Most of issues don't have any solutions and are not solved and no any
sense sugestions.
What I discover..
This is happen when we often doing makemigrations and migrate with
variable way as
`makemigrations myapp` and `migrate`
or
`makemigrations myapp` and `migrate myapp`
or
`makemigrations ` and `migrate myapp`
or
`makemigrations ` and `migrate`
The change db from sqlite to mysql and in diffrent way made this same bug.
Some times `python -mpip install --force-reinstall -I django` solved
error, in other situations not.. don't know why and what is relation in
this, but reading sugestions 2 times this helped me, and in next progress
of project not.
The cmd `python manage.py runserver` doing this error, but e.q. this same
cmd via Visual Studio Code not return this errors
https://github.com/microsoft/ptvsd/issues/1866
Adding parameter `python manage.py runserver --nothreading` still this
same error but `python manage.py runserver --noreload` ommiting error in
case that working with this mode in dev is not comfy.
Coz VSC has some bug in debug around static then must fighting with this
all. Django made me sad :(
