MATLAB R2022a error when opening Add-Ons Explorer (Windows 10 Machine)

73 views (last 30 days)
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.

Hello, I am getting this same error. How do I navigate to the properties window?

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.

I have the same problem.
The error code is below and I am having trouble opening the add-on window.
エラー: matlab.internal.cef.webwindow/errorOnInValidWindow (1559)
Webwindow が有効ではありません。ユーザーによって閉じられているか、処理が終了しています。
エラー: matlab.internal.cef.webwindow/bringToFront (668)
obj.errorOnInValidWindow()
エラー: matlab.internal.webwindow/bringToFront (223)
bringToFront(obj.impl)
エラー: matlab.internal.addons.AddOnsWindow/bringToFront (74)
obj.webwindow.bringToFront();
エラー: matlab.internal.addons.Explorer/bringToFront (73)
obj.addOnsWindowInstance.bringToFront();
エラー: matlab.internal.addons.launchers.showExplorer (138)
matlab.internal.addons.Explorer.getInstance.bringToFront;
I have repeatedly uninstalled and installed and then tried the 2021b and 2022b versions but the problem was not resolved.
