When I open the Add-on Explorer, it only shows a blank window. But if I move around the cursor, it does change its look (from 'Normal Select' to 'Link Select', as the picture shows) at some places.
Besides, Add-on Manager shows the same problem, while the 'Package App' window works fine. I tried reinstall MATLAB, but the problem remained. (I'm using MATLAB R2018a on Windows 10 64-bit) Recently I used an extended monitor, and I wonder if that's the cause of the problem. In case there is no solution, can I install a .mlpkginstall file manually?

I have a similar problem on Linux. Although in my case the window is black and unresponsive. Starting Matlab with "matlab -softwareopengl" didn't help either.

Please try to run the following in the MATLAB Command Window:
>> opengl software
And then try opening the Add on explorer again. It worked for me.
If that works, you can save the preference so that MATLAB always opens with Software OpenGL by running:
>> opengl('save','software')

Hi,
I had the same problem. These commands doesn't helped me. In my case the problem was due to an external screen which I use on my laptop. After disconnecting the latter, the problem is solved.

Same. Switching to one monitor mode would display the content of the Add-on page.

Hi Xiatong,
Please first make sure this is not an issue caused by OS environment, you could try installation on another PC if allowed to confirm if this is reproducible at your side, otherwise, reinstall OS and MATLAB usually would resolve the issue.

For MATLAB 2022B, run the below command before launching MATLAB.
xhost +SI:localuser:root
It worked for me.
