[Python] My django app broke after windows reinstallation

Yesterday I reinstalled Windows and now my Django project’s Google login (using django-allauth v0.65.11) stopped working.

I use a virtual environment and reinstalled the same dependencies (pip freeze matches exactly). Before the Windows reinstall, everything worked fine.
Now, when I try to log in with Google, I get this error on the website:

Third-Party Login Failure
An error occurred while attempting to login via your third-party account.


The server console only shows this:

[28/Aug/2025 14:57:57] "GET /accounts/google/login/callback/?state=h7XieABcvxcuZgpX&code=4%2F0AVMBsJjAduD5uQ3tC334RqFwdAan0rK229B-qJzKmTizkmO68aNYOHyq26FIaYf_WwVYDA&scope=email+profile+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.profile+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.email+openid&authuser=1&prompt=consent HTTP/1.1" 200 1152


No errors, no traceback, nothing.
Even my custom adapter methods:


class MySocialAccountAdapter(DefaultSocialAccountAdapter):
def pre_social_login(self, request, sociallogin):
print(">>> pre_social_login <<<")
def populate_user(self, request, sociallogin, data):
print(">>> populate_user <<<")


are never called.

What I’ve tried:

• 
  Confirmed Google OAuth credentials in Google Cloud Console
  
  
• 
  Checked that SOCIALACCOUNT_ADAPTER path in settings.py is correct
  
  
• 
  Deleted and re-migrated the database
  
  
• 
  Created a fresh Django project and copied code — issue persists
  
  
• 
  Reinstalled Python (3.12) and all dependencies

I've tried to enable logging:

LOGGING = {
"version": 1,
"disable_existing_loggers": False,
"handlers": {"console": {"class": "logging.StreamHandler"}},
"loggers": {"allauth": {"handlers": ["console"], "level": "DEBUG"}},
}


nothing showed up.
