This issue may be due to a problem with the Service Host required for MATLAB. Please try uninstalling and reinstalling the Service Host to see if the issue persists. This is different from reinstalling MATLAB itself; MATLAB does not need to be uninstalled in order to uninstall and reinstall the Service Host.

For instructions on uninstalling/reinstalling the Service Host, please see the following MATLAB Answer:
