Unable to access control panel

While doing SEO activities, I accidentally hit “save” in the WordPress settings menu after deleting the word “wordpress/” off the end of my website name. Now I am unable to get into my WordPress control panel to fix it or into any of my pages. Bad news . . .

This is what the site name should be . . . https://krausgrafik.com/wordpress/ . . . but that doesn’t get me to the full WordPress site.

Is there any way to fix this? If I go into my ISP server is there some folder or database where I could edit the code directly to add the word back in so it will work again? WordPress is listed as an add-on in my control panel with Verio but clicking on that just allows me to disable or uninstall. I don’t see anywhere all the actual page files are stored.

Do I have to reinstall WordPress? If I do, do I lose all my pages?
