The HP Smart app on my Macbook Air with Catalina OS won't open

[CombatCritic]

The HP Smart app on my Macbook Air with Catalina OS won't open.

When I click on the Smart app icon, it starts to open and then disappears.

I have deleted the app, it won't let me uninstall it, emptied the Trash and restarted the computer, but the problem persists.

I tried deleting the printer(s) in Preferences and adding it again following the instructions from another post solution, but that didn't work either.

Thank you!
