Error when primary site address have been replaced with the Domain I purchase and connected to wordpress

Hi Everyone, I just recently connected my wordpress site to the domain I purchase on godaddy and under WordPress > Domain, it says that it was active. Now the issue is since by default my samplesitecom.wpstaging.com is the primary site, I set it to the domain I connected which is the samplesite.com, after I did that everything om the dashboard cannot be edited or visited, what should I do?

Thank you
