What causes this problem? Unable to open Simulink program.

I try to open the simulink section but i got this message from command window of matlab as shown in below. This cause from the license or the process to install MATLAB & SIMULINK not correct.

Warning: Error using matlab.internal.cef.webwindow

MATLABWindow application failed to launch. Unable to launch the MATLAB Window application. The exit code was: -1073741819

Hi,

I understand that when you try to open Simulink, you see various error messages in MATLAB's Command Window.

This sequence of error messages is likely caused by an antivirus software preventing MATLAB's access to the "MATLABWindow.exe" file. Please refer to this previous MATLAB Answer for more details and possible workarounds: https://www.mathworks.com/matlabcentral/answers/1874312-trend-micro-s-security-software-prevents-matlab-s-access-to-matlabwindow-exe-file-inhibiting-web

Hope this helps!

Best, Shivang
