Take a break from reading. Watch a movie, take long walks, go shopping, whatever. Don't read. Be bored for a bit.

Then go to a library/bookstore, browse a bit and pick something that sounds interesting to you. Don't google reviews, don't ask the internet (Goodreads, Reddit, etc) if they think it's good. Just pick something that speaks to you.

Eventually, you'll come across a book that you'll want to read and your slump will be over.

Sometimes I read a book and also listen to an audiobook. Often they are fiction and non-fiction. So when I read two books, it's always either an entirely different genre or medium.

I studied literature, so sometimes I also read one book for class and another for fun.

Are they perhaps talking about metafictional books and metafictional elements in books? In other words, novels that know that they are novels and comment on that in the text? I personally enjoy those but can understand why others night find it annoying.

I'm happy to hear that, thank you for this feedback! :)

Ed Yong's book is excellent, I loved it too.

Very different but also a lot of fun: You Look Like a Thing and I Love You by Janelle Shane, where she explains how AI works and all the weird things it does.

There are groups in Goodreads??? Where?? How? What do they do?

Edit: aahh that's why I never came across the groups on the App: on Android, "it's not currently possible to join new groups using the app. We recommend using our desktop or mobile sites to do this."

My book edition has a family tree in it and I find it so helpful! I've read the book multiple times and I still get confused lol

Oh that's a great idea about a DNF Goodreads shelf! Thanks!
