I recently downloaded Unity version 5.6.5 through Unity Hub to work on a mod, but I am unable to open it because it requires me to sign in with my unity account. I normally sign in with Google, but it does not give me the option. When trying to use my google email and password, it shows an invalid. I know using a newer version gives me the option to sign in with google, but I need to use version 5.6.5 for the mod. Is there a way to sign in using my google account? Image attached below.
While the hub is capable of opening content for Unity version 5.6, the editor uses its own integrated launcher. Kindly note that 5.6 likely not supported now.
