App Designer window is not appearing on my screen and appears blank on my Windows toolbar

I am using MATLAB R2022a, and I am trying to open the App Designer. However, whenever I try to launch it, nothing appears on my screen. On the Windows toolbar at the bottom of the screen, I can hover over the MATLAB program and see a window for the opened App Designer. However, it appears blank, and even clicking directly on this blank window from the toolbar does not open anything.

The same issue occurs when I try to open the App Designer with both approaches detailed below:

1. Executing the following command in the MATLAB Command Window to launch App Designer:

>> appdesigner

2. Navigate to the Apps tab in MATLAB and press the Design App button.

How can I resolve this issue?

This issue may be resolved by the following steps:

1. Hover over the MATLAB program icon on the Windows toolbar.
2. Hover over the blank App Designer window from the pop-up windows of the MATLAB program from the toolbar and right-click.
3. Press the Maximize button.

This will enlarge the chosen window to fill your current screen, and this may populate the window as it should appear and no longer appear blank.

In MATLAB R2016b or older releases, you may also try executing the following commands at the MATLAB command window to help resolve the issue:

>> rmpref('appdesigner', 'Position'); 
>> rmpref('appdesigner', 'Maximized');
