You can try to troubleshoot the issue by following the steps below:

• Before modifying the search path, it is important to take a backup of your 'pathdef.m' file, which can be located by using the command:

>>  which -all pathdef

Before proceeding, ensure that you make a safe copy of the file by copying it to a folder outside of your MATLAB path.

• After taking the backup, please execute the following commands in the MATLAB Command Window to restore the default MATLAB search path and rehash the toolbox cache:

>> restoredefaultpath
>> rehash toolboxcache

• After this step, please use MATLAB/Simulink to see if the issue occurs again. If the issue is resolved, then you may want to save the new MATLAB search path by executing the following command:

>> savepath

NOTE: This will remove any custom paths you may have created. The following MATLAB Answers post is an additional resource on how to back them up:
