Yeah, it fixed my problem.

The Solution is

You might be able to solve the error by simply deleting your User Profile Service Application.

Indeed, this is not best practice obviously, but if you need to get back to working fast, this is a quick solution (hence, this is a ”Quick tip” post).

In order to delete the Service, you need to visit the Central Administration of your SP2010 installation, at the page where the listing of your Service Applications resides (Central Administration > Application Management > Manage Service Applications)

ie. /_admin/ServiceApplications.aspx

Select the User Profiles Service Application proxy and then, from the ribbon options, select Delete.

As I said before, this is hardly best practice but, still, it will help you get back to work until a more suitable solution comes around.
