Unable to open Add-On Explorer

Hi,

I'm trying to access the Addon Explorer in order to install the Arduino Support Package and I get this error:

Dot indexing is not supported for variables of this type.

Error in matlab.internal.addons.AddOnsWindow/bringToFront (line 74)
            obj.webwindow.bringToFront();

Error in matlab.internal.addons.Explorer/bringToFront (line 73)
            obj.addOnsWindowInstance.bringToFront();

Error in matlab.internal.addons.launchers.showExplorer (line 138)
            matlab.internal.addons.Explorer.getInstance.bringToFront;

I reset the MATLAB Preferences and also reinstalled in entirely. Both attempts did not fix the issue.

I'd appreciate your help.

Thank you.
