Clicking on "Get New..." from Global Theme -> no pop-up

Just downloaded KDE Neon and tried to change the themes by going to → Global Theme → Get New… → expected a pop-up to let me choose the themes.
Sadly to no avail, I come from EndeavourOS - so I am familiar with KDE and know that there should be a popup.

Looking forward to any kind of help.
Cheers

Does your distro have Qt 6.7? If so this is probably 479816 – Get New... buttons not working with Qt 6.7.
