"Warning: Name is nonexistent or not a directory" appears after MATLAB start

Starting MATLAB R2019b from the container image (instead of the MATLAB R2019b available directly on ursus7) might lead to warnings about missing toolboxes

MATLAB is selecting SOFTWARE OPENGL rendering.

The cause of this is an "incompatibility" of already existing MATLAB configuration files in the user $HOME directory with the "incomplete" MATLAB R2019b installation in the container image.

To simplify the container image setup on the operating system side, the MATLAB Compiler and Compiler SDK toolboxes have not been installed for now. These should, of course, be added. (Note to myself: The required information on compatible/recommended compilers are available here: https://de.mathworks.com/support/requirements/previous-releases.html)

(How to solve this in the meantime is for example described here: https://de.mathworks.com/matlabcentral/answers/94040-why-do-i-receive-the-warning-message-warning-name-is-nonexistent-or-not-a-directory-when-i)
