Solution: Checked a lot of information on the external network, some people said that it can be solved by cleaning the project, but my program still does not run normally, and then I saw a solution to Expected BEGIN_OBJECT but was STRING on Stack Overflow. I received it. Inspiration

I added two lines of code to my program

and then solved it. I hope to inspire you
