How to delete a personalized view in Buyer work center from Backend

Hello Experts,

I have a situation.

one of our user has created a custom view in Buyer work center using personalize button given.

he had selected all the columns available in that view and made it default view for him.

now when he logs into buyer work center it doesn't load because of large amount of data in the custom view and gets timed out.

I want to delete this view or want to be removed from default view. but i am not able to do it since i am not able to reach that page because of time out.
