Incase anyone else runs into this error, it is likely caused by preexisting credentials on your computer. To fix this, follow these steps:
- Search for and open "Credential Manager" in the windows search bar.
- Select "Windows Credentials".
- Under "Generic Credentials", find "git:https://github.com" and click on it.
- Select "Remove".
After this, a login pop up will now happen when sending the push command in git for the first time.
