I installed the kde-plasma-desktop package to experiment with KDE, while also maintaining GNOME on my system, which is version 23.10. KDE launches without any issues, but I encountered a problem when I tried to log into GNOME. The App Center icon on the dock has disappeared and has been replaced with a dark square and an exclamation point, as shown in the picture below. Furthermore, after booting, if I click on the grey box with the exclamation icon, it takes nearly 45 seconds for the App Center to open, even though it does eventually load. This delay was not present before the installation of KDE. I appreciate any assistance you can provide. Thank you!
