Modifying KDE Settings As a Blind User

Hi all. New Linux user here. I recently installed Linux on an old 
computer. At first, I had Ubuntu Mate, but after experiencing frequent 
Orca freezes, I switched my desktop environment to KDE Plasma. I like 
the desktop, but I've found that the system settings seem to be 
inaccessible with Orca. It just says "layered pane," and will only read 
things like the OK, cancel, help, and close buttons. The terminal 
emulator was also inaccessible, but I fixed that by reinstalling the 
Mate terminal. Is there a way to make the settings app accessible, or is 
there another way to modify settings? Right now, I'm particularly 
interested in changing default apps and making it so I automatically log 
into the computer. Thanks.
