I spend 90 mins on the line with TT support. Very nice person who was very helpful in getting this issue escalated through a number of other people/hoops to the "resolution desk". At every step to that point, the reflexive response was "TT only supports N years" of Desktop. It is frustrating to continually explain that I am not seeking support, I only want the program to run, as it did previously. (Mac user and like someone else on this thread, I have a new computer). And, btw, 2017, 2018, 2020.. all work no problem. In the end, they offered no solution. This is an absurd Intuit problem.
