KDE application menu does not store power options after a system restart

Steps to replicate: Add power options (e.g. Power off, Sleep, Restart etc.) to the applications menu favorites section. Restart the system. Open Applications menu - the added power options are now gone from the favorites section (only Log out remains).

Operating System: Manjaro Linux
KDE Plasma Version: 5.23.3
KDE Frameworks Version: 5.88.0
Qt Version: 5.15.2
Kernel Version: 5.15.2-2-MANJARO (64-bit)

Processors: 8 × Intel® Core™ i7-9700K CPU @ 3.60GHz
Memory: 31,2 GiB of RAM

I have no issue. I do not know it can help.

  • rm ~/.config/Trolltech.conf

  • kbuildsycoca5 --noincremental

  • Optionally, empty the ~/.cache/ folder contents, however, this will also clear the cache of other applications: rm -rf ~/.cache/*

  • reboot.

Thanks for suggestion.
Tried that.
Made no difference.
