Caught "std::exception" Exception message is:

An error occurred while initializing child process: While attempting to execute "C:\Program Files\MATLAB\R2023a\bin\win64\mwdocsearch.exe server -m C:\Program Files\MATLAB\R2023a -p 56316 -v C:\Users\28395\AppData\Local\Temp\ -t 9132 0 1 0 0 0": CreateProcessW: 拒绝访问。 [system:5]

It pop out every time I launch the Matlab today.

Some anti-virus systems sometimes believe that parts of MATLAB / Simulink are potential malware, so sometimes you need to exempt MATLAB from being scanned and then reinstall parts of it.

Hi Fu,

It looks like there is an issue with initializing the child process and the error message indicates that the operating system is denying access to execute "C:\Program Files\MATLAB\R2023a\bin\win64\mwdocsearch.exe" due to permission related issues.

You could try running Matlab as an "Administrator" and check if the issue is resolved or not. To run as an administrator, right-click on the Matlab icon and select "Run as administrator" option from the contextual menu.

If running as an administrator doesn't resolve the issue, you could also try disabling your antivirus software temporarily as it could be blocking the application from executing.

If the above solutions do not work, you could consider repairing or reinstalling MATLAB to resolve any potential corrupt installation-related issues.

Hope this helps!
