I found that they do stop working because the update server is no longer available so the program cannot be opened. at least that has been my experience for 2019/2020/2021 even though they were up to date with the state installed. What I got was a screen to enter the license code but even after entering that, i got an error message
the easiest way for @ZbysioSie to check is to try to open the app and see what happens.
