First, it’s just a warning. You didn’t say what does not work.
Second, browse this as it’s obviously related to the upgrade. Check all your .cfg files, remote binding download settings in particular.
If that does not help, find out what binding is causing this by removing your bindings in chunks or one by the other.
To sum up your request (see title), reinstall is NOT a good idea because you don’t know what is causing your issue and it’ll reappear if you restore all of your config.
