There is no Atmosphere and Hekate yet for 20.0.0

It's in the article that the above user posted. You clearly didn't pay attention.

The solution is surprisingly simple but you will be hurting until new CFW that supports HOS20 get released, which I suppose is usually very soon, I won't be surprised by the time you read this post it is already done, so you won't be suffering for long. If you are still having trouble ask again after that.

PS: Just a small technical tidbit. Warmboot is loading from sysnand which you have changed by performing the update.
