This issue could possibly be due to MATLAB’s search path being incorrectly set during the base installation.
A possible workaround to resolve this issue can be by launching MATLAB without desktop and then restoring the default MATLAB search path and rehashing the toolbox cache.
1) Open MATLAB with the -nodesktop start-up flag. In the Command Prompt, enter:
2) Enter the following commands into the MATLAB Command Window, one after the other:
>> rehash toolboxcache
I hope this information resolves your issue.
