WE TRIED ALL THIS STUFF BELOW: "You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.

See "Visual Studio 2015, 2017 and 2019":

On computer startup, there's a message like the one above Tthat pops up, but related to itunes: "...especially VCRUNTIME140_1.dll."

Several hours wasted already trying to fix this over two weeks. It finally worked okay the first time, but then I X'd out a couple of small boxes that popped up on the desktop on the next startup without paying attention to what they said. Back to being messed up. My bad.
