Welcome to the Q&A Forum

It seems like Google only has a handful of distinct pages indexed at the moment - whereas bing has about 10x as many. So that seems to indicate something wrong specifically for Google. I'd start by checking your search console - are there any errors? If you use the URL inspection tool and visit the URL in question (studyplaces.com/15-best-minors-for-business-majors/) does it tell you why it has been canonicalised? What happens if you view the page as Google saw it? Is there any chance that you are blocking googlebot / cloaking in any way? Have you had any website outages or downtime? As others noted, your about page is now missing - did you do that deliberately to see if it resolved this issue?
