kf.xmlgui: KActionCollection::setComponentName does not work on a KActionCollection containing actions! "dolphin"
kf.dbusaddons: 'kdeinit5' is taking more than 30 seconds to start.
In emacs, the command M-x dired fires dired up in split seconds with all file names in the current directory.

That “kf.xmlgui:” message I see also on Tumbleweed so that is very likely not related to the problem.
As multiple applications have the problem it has likely something to do with file/network access.
You can run:
strace -t -f -o /tmp/dolphin.strace dolphin
That will create a huge text file containing all OS calls including file/network access. Have a look at the time stamps and check if you see large gaps. If so, try to see what is the root cause for these gaps.
You can consider sharing the part file via https://susepaste.org/, keep in mind it contains all files/network locations that you might want to keep private.
For your reference dolphin takes about 3 seconds for me and closing it immediately gives my (only things > 5%):
