After starting up Matlab I get the following errors in the command window:

It seems like the complete Matlab path is destroyed. Please explain, what has happened before. Is this a fresh installation? Did you edit the pathdef.m file? Did you shaddow this file by a personal version, which does not include the toolbox folders?
See: https://www.mathworks.com/help/matlab/ref/restoredefaultpath.html
This command should fix a damaged path.
