Lost everything

Help please-

I am going to be as specific as i can here.

I was doing great using Kadence Theme ‘Virtue’ theme with wordpress when i noticed my logo would trigger a hand when hovered over it. When i clicked it, i would see the initial wp page ‘hello world’.

i then went into settings, general and changed the url from my website name/**** to just my website name. took out the letters after my .com/****. thought this might correct the logo issue. well now i have nothing. the message said there was a reset and then went to an error page. can’t get back it. days of work lost. site is http://www.starbrightusa.com shows some weird format of my site. really messed this up. sad part was i was getting a nice handle on building my site and having fun doing it.

what do i do to get back on track. how do i get back to wp dashboard i’ve been using all along. really appreciate any help offered here. i’m just lost at this point. Many thanks in advance.
