Unity 2018.1.0b13 Loading Script Assembly "Assets/System.Data.dll" failed!

After updating to 2018.1.0b13 and trying to use Stable(.NET4.X) I’m getting these errors that are causing my build not to work.

Loading script assembly "Assets/System.Data.dll" failed! Loading script assembly "Assets/System.Data.Linq.dll" failed! Loading script assembly "Assets/I18N.West.dll" failed! Loading script assembly "Assets/I18N.dll" failed!

I’ve looked everywhere for what could be causing this, I assume it’s still because 2018 is in beta.

Any help would be greatly appreciated.
