Google search does not display the website

Hello,

Unless you enter my website’s URL into Google, it is not viewable. My website is not found even with extremely straightforward searches (such as my name (website name) – name of project). I downloaded Google Console in an attempt to investigate the reason. I have no idea how to fix the sitemap error or whether indexing is the actual issue, as it informs me that the map is HTML. Any assistance is greatly appreciated. Regards
