All links point to previous version of the homepage

I am building a new site. I theme I am using is Twenty Twenty-Two. I am running wordpress 5.9.3. I have updated my home page several times. Then I started creating other pages. I added navigation links and button links to connect my home page to all of the pages I created.

This is the problem.
1. Most of the links connect me to a previous version of my homepage. One link points to a 404 page.
2. When I go to my page list, when I click edit it takes me to the pages that I have built. But when I click preview on any of the pages on the list; even pages that I have not edited, it takes me to the same previous version of my homepage.
3. I confirmed that all of the page permalinks were specific to the pages that I edited but all of the different links show the previous version of my homepage, not my Blog page, or About page.
4. When I paste my page address in the address line of my browser it takes me to the previous version of my homepage, not to the page I edited in WordPress.
5. All links point to the same previous version of my homepage.

My home page is:
https://box5659.temp.domains/~terrywan/
My other pages are:
https://box5659.temp.domains/~terrywan/about/
https://box5659.temp.domains/~terrywan/gallery/ etc.

Am I doing something wrong or is there a problem with WordPress?

I read that I need to create a static homepage when I want to use other pages for blogging purposes but assumed that this info was related to the old customizer version of WordPress. I see no way to do that using the block editor.

Thanks in advance for your help!
