Localhost page loads blank screen

I am currently taking the react 18 course and am on the final project (build a game discovery website). I have followed his instructions to the letter and have no compilation errors in my code (nothing underlined in red, no errors thrown). however, when I load the localhost, loading completes correctly (skeletons show up, dark mode switch, logo in the corner) but as soon as loading finishes all that disappears and I’m left with a blank screen. I’m on lesson 18 of the final section. here are some screenshots of what I’m experiencing (I can only put one screen shot, apparently, so here’s the blank screen):
