Biz Boost Theme Indexing Issues ?

Hello, I recently created a website using Biz Boost theme and integrated the Yoast SEO plugin for optimization. However, I've encountered an issue where the main page is not visible in the pages section, making it impossible to edit the SEO settings for it. Despite ensuring the website is crawlable, it doesn't appear in Google search results. I'm seeking assistance to resolve this matter. Any help would be greatly appreciated.
