404 error despite deployment successful from uploaded files

Hello! I am new to this whole space, so I might be missing something very obvious. I created a github repository from a zip file that was sent to me, and followed the instructions to create cloudflare pages and deploy the project. I kept getting the attached error when I tried to deploy that page. But, when I uploaded the files directly to cloudflare, the deployment was successful but the URL gave me a 404 error. Any help would be appreciated!!

Can you share the public repository you are deploying from @laurel2?
