Can you please share valid WP-ADMIN Login details of your Site so that we can proceed further and check the mentioned issue on your Site and assist you accordingly.
Sorry to say but as far as we are seeing your Site, the Homepage view is appearing fine while we are viewing with Logged In but as far as we are viewing without Logged In, it is showing Twenty Twenty Two theme page.
But when we cleared the Page with Hard Cache and then the Site Preview was appearing fine like the Theme one. So, it seems to be the Cache issue on your Site. So, can you please ask your Hosting Provider to once try to disable the CDN/Cloudflare on your Site for the time being while you are Customizing your Site (if it is enabled, if not then ignore this part), flush it completely along with that completely clear your browser as well as Site and Server cache and then check back your Site again. Hopefully, you won’t find the issue again.
