Broken Permalinks

Hello,

I have created permalinks for my posts and have placed those permalinks onto my homepage. I have about 12 of these permalinks to different posts, but after I placed them as hyperlinks into this post and attempted to test my website, I realized that about every other one of the is broken and leads to an error page saying “not found.”

Here is my homepage, notice how some links work in this main post while others don’t: https://www.reviewcaptain.com/

What is going on here? Any help would be greatly appreciated!
