Hi @Div12345, it appears that the primary issue here is that MATLAB is attempting to launch the New Desktop experience. Unfortunately, the VS Code extension currently does not work with MATLAB when the New Desktop is enabled. The only workaround at this time is to disable the New Desktop. We are actively working to resolve this issue, and plan to release that in a future update. (This is tracked by #24)

The issue with mlint is a separate known issue where the mlint executable cannot be found on Windows. This is also something we are working to resolve in an upcoming release of the extension. I have created #83 to track this. Once the New Desktop has been disabled, you should have access to linting when MATLAB is connected - this issue only exists when MATLAB is not connected.
