Failed to open Add-On manager and install Add-Ons

I'm currently running Matlab R2021b on a Win10 machine but experiencing the same issues with Matlab R2020b on the same machine. I tried to open the Addon Manager to install another basemap but I get the following errors:

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.Manager/show (line 59)

obj.addOnsWindowInstance.bringToFront();

Error in matlab.internal.addons.launchers.showManager (line 80)

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

Error using str2double (line 215)

STR2DOUBLE: invalid input argument

Error in matlab.net.URI/set.Port (line 393)

Error in matlab.net.URI/parse (line 1191)

Error in matlab.net.URI (line 874)

obj = obj.parse(dest, literal);

Error in matlab.internal.addons.AddOnWindowUrl/generate (line 24)

url = matlab.net.URI(this.baseUrl);

Error in getExplorerUrl/getConnectorUrlForMatlab (line 49)

url = urlGenerator.generate.EncodedURI;

Error in getExplorerUrl/getConnectorUrls (line 43)

connectorUrls.matlab = getConnectorUrlForMatlab();

Error in getExplorerUrl (line 20)

connectorUrls = jsonencode(getConnectorUrls());

Error in matlab.internal.addons.Explorer/show (line 63)

url = char(getExplorerUrl(navigationData));

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

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

Another way i tried was downloading the the basemap as an ".mlpkginstall"-File from Mathworks file exchange but that's producing errors as well:

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.Manager/show (line 59)

obj.addOnsWindowInstance.bringToFront();

Error in matlab.internal.addons.launchers.showManager (line 86)

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

Error in matlab.internal.addons.launchers.showInstallerInManager (line 23)

matlab.internal.addons.launchers.showManager(entryPointIdentifier, 'openUrl', installerUrl);

Are there any settings I might have missed doing? I'm grateful for any help.

I finally made a clean installation of R2021b and find it working as it should. I started adding my "Set Path" Directories and again it wasn't working anymore. Figured out that this toolboxes caused the above described issues https://de.mathworks.com/matlabcentral/fileexchange/46271-electromyographic-signal-analysis-tool-emgat2014

Hi Daniel,

To resolve this issue, regenerate your MATLAB Preferences.

Please follow the mentioned link for more information: How do I regenerate my MATLAB preferences

Hey Anshika,

thanks for the reply. I followed the Instructions to regenaret my Matlab preferences. Which worked well.

Still, I'm not able to open the Add-Ons-Manager. Getting the following errors:

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;

Getting the same error when trying to launch the add-on explorer window. Inserting code below:

Error using strsplit

Too many input arguments.

Error in matlab.net.URI/set.Path (line 432)

obj.Path = strsplit(string(value), '/', 'CollapseDelimiters', false);

Error in matlab.net.URI/parse (line 1202)

obj.Path = parts.Path;

Error in matlab.net.URI (line 874)

obj = obj.parse(dest, literal);

Error in matlab.internal.addons.AddOnWindowUrl/generate (line 26)

url = matlab.net.URI(this.baseUrl, this.queryParams);

Error in getExplorerUrl/getConnectorUrlForMatlab (line 50)

url = urlGenerator.addQueryParameter("useRegFwk", useRegFwk()).generate.EncodedURI;

Error in getExplorerUrl/getConnectorUrls (line 44)

connectorUrls.matlab = getConnectorUrlForMatlab();

Error in getExplorerUrl (line 20)

connectorUrls = jsonencode(getConnectorUrls());

Error in matlab.internal.addons.Explorer/show (line 63)

url = char(getExplorerUrl(navigationData));

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

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

Any advice?
