I tried with both R2019b and R2023b but when running classificationLearner, it crashed with the followings:
Error using matlab.internal.cef.webwindow
MATLABWindow application failed to launch. Unable to launch the MATLABWindow application. The exit code was: -1073741819
Error in matlab.internal.webwindow/createImplementation (line 327)
implObj = matlab.internal.cef.webwindow(varargin{:});
Error in matlab.internal.webwindow (line 163)
obj.impl = obj.createImplementation(varargin{:});
Error in matlab.ui.container.internal.AppContainer/buildWindow (line 2244)
window = matlab.internal.webwindow(url, this.getOpenPort());
Error in matlab.ui.container.internal.AppContainer/set.Visible (line 733)
this.Window = this.buildWindow(windowBounds);
Error in mlearnapp.internal.adapterlayer.ToolGroup/makeVisible (line 217)
this.PrivateToolGroup.Visible = true;
Error in mlearnapp.internal.ui.DialogFactory/createMLearnAppWindow (line 20)

Error in classificationLearner (line 104)
hApp = dialogFactory.createMLearnAppWindow(session, newSessionCreatorFactory, importTestDataCreatorFactory, appTag, appTitleMessage, problemDependentToolstripFactory, metricFactory, mainThreadBusyTracker);
Please help with this issue. Thank you very much!

Are you using any anti-virus software which could potentially cause MATLABWindow.exe to fail to launch? If yes, try adding MATLABWindow.exe to the trusted programs list of their antivirus and see if that helps.

Indeed, I have Trend Micro Security on my computer, which is mandatory within my current workplace; unfortunately, I don't have permission to modify the trusted program list. I will try this with my other computer. Thank you for your prompt reply.

Hi @Hope Pan,
You may be encountering this error since you are using Trend Micro security software. This error occurs because MATLAB utilizes a Chrome-based browser internally for rendering various graphical elements. This functionality may be impeded by Trend Micro’s blocking mechanisms.
You can refer to this MATLAB Answer thread for more information on resolving this issue:
https://www.mathworks.com/matlabcentral/answers/1874312-trend-micro-s-security-software-prevents-matlab-s-access-to-matlabwindow-exe-file-inhibiting-web
If you are not using Trend Micro Security, then you can determine the exact cause of the issue by following the troubleshooting step below:
Run the following command in the MATLAB command window:
cd(matlabroot)
cd bin\win64
!.\MATLABWindow.exe
  • If you receive a blank window that disappears without throwing any error message, then it is likely that the issue you are facing is due to a firewall or an antivirus software blocking MATLAB.
  • If there was a crash or other issues internal to MATLAB, there would be error messages in the logging output. In this case, try reinstalling MATLAB as this may resolve the issue.
Hope this resolves your error!
