MATLAB (R2022a) is giving me this error when I try to open the Add-Ons explorer on a Windows 10 machine:

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 315)

implObj = matlab.internal.cef.webwindow(varargin{:});

Error in matlab.internal.webwindow (line 163)

obj.impl = obj.createImplementation(varargin{:});

Error in matlab.internal.addons.AddOnsWindow (line 41)

obj.webwindow = matlab.internal.webwindow('about:blank', obj.debugPort);

Error in matlab.internal.addons.Explorer/createNewWindow (line 111)

obj.addOnsWindowInstance = matlab.internal.addons.AddOnsWindow(obj.WINDOW_TITLE, clientType, obj.windowStateUtil.getPositionForExplorer);

Error in matlab.internal.addons.Explorer/show (line 62)

obj.createNewWindow;

Error in matlab.internal.addons.launchers.showExplorer (line 140)

matlab.internal.addons.Explorer.getInstance.show(navigationData);

I recently upgraded my Matlab software from R2020a to R2022a, which I'm wondering may have played a role in these errors. I had no issues with R2020a. Not sure if this helps, but I installed R2022a before I uninstalled R2020a.

Hi Ashnith Wickramanayake,

From my understanding of your question, I suggest you to make a clean installation of R2022a and find if it is working. You may find this link helpful, with similar issue due to some of the toolboxes being installed https://de.mathworks.com/matlabcentral/fileexchange/46271-electromyographic-signal-analysis-tool-emgat2014

To install toolboxes and apps manually ,refer to this link:

Thank you for the reply @Adarshini K. I'm afraid I don't see the similar issue in the first link. I will try a clean installation and see if that resolves the issue.
