Well, in my experiences Godaddy is a horrible host and I often refuse to work on peoples websites if they don’t get off Godaddy and use some other host.
Other then that I doubt reinstalling will do anything. Waiting likely isn’t going to do anything either. If you can’t adjust the permissions so that PHP can write to the tmp folder then all I could say is change your PHP session save path to somewhere else outside of your website root folder so it isn’t accessible from the internet and see if that helps. If you can even edit your PHP settings with Godaddy.
