I don't think so, I have about 10 hosts lists and all is fine... But in your case, one of the hosts you have is blocking whatsapp (maybe more than one). Try dissabeling one by one and see which one it is.
People talk about problems that exist with Android 10..
Not only does Adaway not work with Magisk at the moment but also Titanium for example..
