How can I resolve an internal or vault integrity error when using secret management functions in MATLAB?

When I try to run any secret management functions for MATLAB vault (e.g. "getSecret", "setSecret", "listSecret"), I get one of the following errors:

An internal error has occurred. Please contact MathWorks technical support for a resolution.

Vault integrity check failed

Why does this happen, and how can I restore functionality?

This error can occur when a user's secret store is corrupted, so MATLAB cannot validate the secrets anymore.

To get them back into a good state, try the following steps:

1. Shut down all MATLAB, MATLABConnector and MathWorksServiceHost processes and make sure that none of them are running.
2. Delete the credentials folder found in:
   • Windows:   %APPDATA%\MathWorks\credentials
   • Linux:  ~/.matlab/credentials
   • Mac:   ~/Library/Application\ Support/MathWorks/credentials
3. Start MATLAB again. You may be prompted to sign in.

After this, the error should resolve. If it does not, please contact MathWorks Technical Support.
