If I can help just join with the use of the localhost, it will automatically offers you, when you try to signing in the source control. it will open your prefered browser, than join to your github account normally, then inside vscode cancel it and then there will be an option to setup a local server click on it and it should work

If the problem persist, write me email: [email protected] or on discord: nikolajk97

If you choose to write email write to subject Log In VSCODE.

I hope it will work
