Using KDE and having problems in the Add/Remove Software program

When I go into Catagories and scroll down the apps in the Communication & News section the Add/Remove Software program shuts down, or should I say just disappears, when I get to ones starting with the letter S. This is the only place in the program where this occurs. Is anyone else experiencing this problem?

Change the sort order and see what happens. Any other programs running. Check memory usage, temperature. Reboot and run pamac first thing to see what happens. Run it in the terminal so you can see any error messages These are all the sort of things to do when any program acts up. Your first post and you should read Effectively using the forum to get support and provide more system info
