some program launchers in kde menu do not work

[peer]

os: debian 10, kde
VLC does not start from the kde menu anymore. It does start from within the terminal. Reinstalling did not solve the problem

IDLE (python 3.7) did not start from the kde menu also and did start from within the terminal. Reinstalling fixed the issue here

Clementine start sometimes from the menu and sometimes it does not. In the terminal the same behaviour. In the terminal I get the following warning: "incorrect sRGB profile" and I have to enter Ctrl-C to quit the process.. Reinstalling did not help.

I think here are two problems:
1. something wrong inthe kde-menu
2. something wrong with clementine

So much for that theory...

Have you checked the memory health? Faulty RAM can cause strange problems. Also check your drive health.
