First: This problem started only after the latest update -- and EVERY SINGLE update causes multiple problems!
I tried each of your suggestions; the first 2 did not work, so I was delighted when the 3rd one did. However, the 'fix' was only temporary: that is, upon opening Edge, no 'Favorites Bar' appeared, but as soon as I clicked on 'New Tab', it was back again. I just don't want it there at all, and see no benefit of having it taking up room. Has anyone found any other solutions that are permanent? Thanks so much for new suggestions.

Hello Jakmi, :-(

Starting with Windows 10 build 17063 (announced in Windows 10 build 17074) the Favorites Bar will now always automatically show on Start and New tab pages.

If you have build 17713 or later installed, you could use an option in the tutorial below instead to disable the Favorites Bar everywhere in Microsoft Edge.
