Pushing Error - remote: Invalid username or password.

Hi there,

I keep receiving this error.

git -c diff.mnemonicprefix=false -c core.quotepath=false push -v --tags origin master:master
remote: Invalid username or password.
fatal: Authentication failed for 'https://github.com/Fromfame/Dore-2020.git/'
Pushing to https://github.com/Fromfame/Dore-2020.git

I've reconnected my account and refreshed username/passwords. I've contacted Github and they advised to: 

To remove any cached credentials from the Windows Credential Manager

Which hasn't resolved the issue. I'd appreciate advice on what I can do to resolve this.
