Twitter is just an embed. Is it working for you now? Maybe your browser is blocking the embed? What browser are you using?
it's strange, how it's only the twitter column, instagram column once gave me an error message (something about blocking embeds? can't recall) but was at least showing something from instagram, also that went away after a refresh
twitter just has a dull grey background, like the column was left blank or something.
this on edge (inprivate) window, but I face the same error on firefox.
So really there isn't a way to fix it and make it work unless you don't use private mode in FF or unblock it.
But if you don't want to do that, I did add a way to disable Twitter and Instagram from the top right menu dropdown. Try it out and let me know if that solves your problem well.
