I installed cauldron using netinstaller and plasma does not start but icewm does work. Checking on drakrpm I found that task-plasma-minimal was not installed since libaom.so.2 is missing. onlyaom.so.3 is installed. I downloaded MGA8 version and I was able to install task-plasma5-mimimal. Now everything works great. Regard
Fixed by rebuilding libavif (libavif-0.9.2-2.mga9).
