KRunner stops working after pressing an escape key on Plasma 6

Hi! I am using Fedora Linux KDE 40 on my laptop. Since yesterday, I have been observing a weird behavior of Krunner; it suddenly stops working after some time.

From the system monitor, I have checked that an instance of Krunner is running, and inside the /usr/share/dbus-1/services/ directory, the service file for Krunner is present; here are its contents.

[D-BUS Service]
Exec=/usr/bin/krunner --daemon

I have assigned the shortcut Alt + space to launch Krunner. For the first 2 to 3 times; it launches properly. However, when I hit the escape key or a mouse click to close the pop-up, the pop-up of Krunner does not launch anymore.

Which issue might be causing this annoyance? Any help on this would be appreciated.
