When I start a Whonix workstation, no application opens via the main menu. My only solution is to open an application and use the qube manager’s tray system to open a terminal or file manager. Sometimes the file manager doesn’t even open. It only does this with the whonix, the rest works normally.
Everything is up to date. I created a new Whonix Qubes without changing any parameters, same thing. Temporary Whonix doesn’t have this problem.

The problem is with Qubes OS. Shortcuts from the main menu of Qubes OS don’t work, while from the status bar of Qubes Manager, launching doesn’t cause any problems.
I would try refreshing the applicatiom menu.
Qubes Manager > qube > Settings > Applications > Refresh applications
If you’ve got stale entries in the list, I suppose they may show up in the application menu but be ineffective.
I’m not sure when applications entries become stale, but I know it can happen in some (perfectly normal) circumstances.
