How do I fix the Simulink StartPage error?

When I open matlab R2023a in Windows 11 and click on the simulink tab. I recieve these errors.

Warning: Unable to resolve the name 'sltemplate.internal.Registrar.warmupCache'.

Error in sltemplate.ui.StartPage

Execution of script get_param as a function is not supported:

C:\Program Files\MATLAB\R2023a\toolbox\simulink\core\api\get_param.m

Error in gcs (line 13)

cursys = get_param(0,'CurrentSystem');

I have tried gving system access to the program and installing additional Simulink packages. What Am I doing wrong?

Hi Devon,

I understand that you are trying to open simulink and you are facing the above error.

The default paths of MATLAB may not be configured properly on your workstation. ITo reset them, please proceed with the following steps:

In MATLAB, type the commands to restore the application path:

>> rehash toolboxcache
>> restoredefaultpath
>> matlabrc
>> savepath

Any custom path will be overwritten but you can make a backup as described in the article here.

"restoredefaultpath" path will reset paths for all toolboxes/addons. Therefore, if a third party toolbox is installed which doesn't come from MathWorks, you will have to reinstall that toolbox.
