This error occurs if the MathWorks Service Host attempts to launch when there is already an instance of the service host running. As a result, MATLAB fails to start, and errors out with this message.

The solution in this case would be to reinstall the MathWorks Service Host using the instructions from the article linked below. Please make sure the steps are followed carefully, as there is a chance the error will continue to persist if the instructions are not followed properly.

How do I uninstall and reinstall MathWorks Service Host?
