Error opening "Get Hardware Support Packages" (exit code -1073741819)

I am trying to open the "Get Hardware Support Packages" window in Windows 11 with Matlab 2023a. When I do so, I get the following error:

Error using showError

MATLABWindow application failed to launch. Unable to launch the MATLABWindow

application. The exit code was: -1073741819

Error in matlab.addons.supportpackage.internal.explorer.showAllHardwareSupportPackages (line 10)

showError(exception);

And cannot proceed to download the hardware support for Arduino.

It is a fresh install of Matlab 2023 and a recent install of Windows 11. I have never seen this error on previous Windows 10 or macOS installs.

Hi,

The error you encountered has already been in the following MATLAB answer, please go through it.

I cannot run the MATLABwindow application (on Windows 11) - MATLAB Answers - MATLAB Central (mathworks.com)

Thank you for pointing that out Mayank as I hadn't seen that post.

Since posting I did not run Matlab 2023a. I've rebooted a few times and run other applications. Now, I have reopened Matlab 2023a and also opened the I just opened it. Then, I was able to open the Add-ons menu, as well as the Get Hardware Support Packages window without a problem.

Very strange. I checked Windows Defender's firewall and Matlab is not listed. It doesn't appear at all and there is no entry for Matlab.

However, it appears to be working correctly now.
