Persistent error messages upon opening new MATLAB R2020a download

I just downloaded R2020a onto my new computer with my school's license. However, every time I open it up, I'm bombarded with several error messages and a host of Warning message lines of text. I can clear all of this to get it out of the way, but from then on, every time I try to do anything (from typing a simple addition equation to, to changing the path/folder I'm in, to loading a .m file or variable) then I get an error message reading:

unrecognized function or variable "settings"

Does anyone know why this is happening and/or how to fix it?

After fiddling with it, the error message has now switched to:

unrecognized function or variable 'matlab.internal.validation.propertyValidatorException'

When I try to click on "Request Support" I get an error message reading:

Unable to resolve the name connector.ensureServiceOn

Any help would be greatly appreciated!

Hi kellie,

The above issue of unrecognized function or variable "settings" can happen if the MATLAB unables to find ‘settings.m’ file. There can two reasons.

1. It does not exist
2. It is not on the search path

You can try these three commands and see if it resolves the issue.

>> restoredefaultpath  
>> rehash toolboxcache 
>> savepath
