Slow initialization at startup during the “Ready” step
I have installed Matlab R2024b on a Kubuntu 24.10 system. I installed only Matlab without an Add-ons and had no trouble during installation. Starting the program results in a long initialization time. I tracked the initialization process with the -timing flag. This results in the following output:

As visible, the last step consumes most of the time. Running the program bare with the -nojvm flag results in a quick start (3.92 s) . I already tried to increase the Java Memory heap space, as suggested in https://de.mathworks.com/matlabcentral/answers/1956139-slow-java-initialization-during-startup and tried several solutions from https://de.mathworks.com/matlabcentral/answers/92566-why-does-matlab-get-stuck-in-the-initializing-or-busy-state-or-take-a-long-time-to-start without improving the starting time.
