Takes a long time to open or won't open at all?

When I double-click on ProSeries Basic 2020 now, the little blue Microsoft wheel thing spins for 1 second, then disappears. Nothing shows in Task Manager. It's dead.

When I double-click on ProSeries Basic 2019, it shows in Task Manager, then opens as usual.

So mine isn't a case of taking a long time to open. It's dead. It's not opening at all. Is yours opening after several minutes or so? Or not opening at all?
