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.

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.
