KWalletManager 24.08.0 didn't start when run from the Application Launcher menu with the error notification Launching KWalletManager (Failed): The name is not activatable in Plasma 6.1.4 on Wayland in a Fedora 41 KDE installation. The KWalletManager Application Launcher menu entry points to ~/.local/share/applications/org.kde.kwalletmanager.desktop with the name org.kde.kwalletmanager in the General tab of its Properties window which was created after the time of the update to KDE Gear 24.08.0. KWalletManager 24.08.0 started normally when I ran it from the System Settings KDE Wallet page's Launch Wallet Manager and with kwalletmanager5 in Konsole.

This problem didn't happen with KWalletManager 24.05.2 which has /usr/share/applications/org.kde.kwalletmanager5.desktop with the name org.kde.kwalletmanager5. The name change to org.kde.kwalletmanager in the desktop file might be involved. The commit Fix desktop file name https://invent.kde.org/utilities/kwalletmanager/-/commit/3478852e6600cbea7e87a32e5d11ca859fa59e1f#9a2aa4db38d3115ed60da621e012c0efc0172aae appeared to change the desktop file name from org.kde.kwalletmanager5.desktop to org.kde.kwalletmanager.desktop


Reproducible: Always

Steps to Reproduce:
1. Boot a Fedora 41 KDE installation with KDE Gear upgraded to 24.08.0
2. Log in to Plasma 6.1.4 on Wayland
3. Open the Application Launcher menu
4. Search for KWalletManager in the Application Launcher menu
5. Select KWalletManager in the Application Launcher menu

Actual Results:  
KWalletManager 24.08.0 didn't start when run from the Application Launcher menu with the error notification Launching KWalletManager (Failed): The name is not activatable


Expected Results:  
KWalletManager 24.08.0 should've started when run from the Application Launcher menu
