Hi Sheng,
If this error occurs when attempting to start MATLAB, there is a possibility of conflict between the MATLABConnector ServiceHost and the MathWorks Service Host.
A possible way to resolve this is to reinstall MathWorks Service Host, please refer the following answer thread to know how to uninstall and reinstall MathWorks Service Host:
If this does not work, please try resetting your local credentials with the following steps:
- Shutdown any running MATLABs, MathWorksServiceHost and MATLABConnector processes.
- Delete their credentials storage folder. It can be found at the following path in MAC OS:
"~/Library/Application Support/MathWorks/credentials"
- Try running MATLAB again.
If this error occurs when attempting to start up MATLAB Drive Connector on macOS, there may be an issue with the secrets file contained with the credentials directory, which may have been deleted or modified. To resolve this issue with secrets file refer the following steps:
- Delete the following directory: /Users/$USER/Library/Application Support/MathWorks/credentials
- Delete the "MathWorks Key" key found in your login keychain in the Keychain Access app under UtilitiesRestart MATLAB Drive Connector.
Hope it helps!
