Syntax error in filename, folder name, or volume label: ‘& lt; frozen importlib._bootstrap & gt;’




Very much I ask for help! I create a website, register and log in, everything seemed to work, but then, apparently, I accidentally changed something and now I get an error “OSError: [WinError 123] Syntax error in the file name, folder name or volume label: ””
If you rummage in the console above, where there is an enumeration of all files, you can find the line ModuleNotFoundError: No module named ‘first.apps.FirstConfig’; ‘first.apps’ is not a package. Probably there is a problem with it, but I can’t find it on my own.
Next, I will provide the files and folder locations

Answer 1, Authority 100%

It turned out that the file apps.py was purified by some way
That’s what inscribed there:

from django.apps import appconfig
Class FirstConfig (AppConfig):
  name = 'first'

Now everything works
