Yup Covid was a problem. The tide had turn on the Economy, even without Covid. He inherited a rebuilt economy from his predecessor. All that is easy to look up, and the financial sector reporting doesn't really change facts around the way the political news media does.COVID had a lot to do with that. If it weren't that the virus can be photographed using electron microscopes, I would have said that COVID was actually a Democrat plot against DJT. But you're off the hook for that one - it has been photographed. Until COVID, the country WAS doing pretty well under his leadership.
Trump did his share of Covid mishandling. There is plenty of blame to go around on that. And you have to wonder if the real plot was to get a segment of our population to not trust vaccines, PPE (personal protection equipment) gear, or government in general, so when the real killer virus comes, many will not believe it.
