App Designer Component Library and Component Browser missing after installing MATLAB 2023b for Mac

I have installed MATLAB 2023b in MacBook Pro with M1 processor. When I open App Designer, the App Designer opens but the Component Library, as well as the Component Browser, are missing. The same issue was discussed for MATLAB 2023a (Why is the Component Library and Component Browser of the App Designer not displayed in MATLAB R2023a?), but I cannot apply the solution, i.e., to find and delete AppDesignerMainPanelLayout.json file, as I cannot find the file altogether. Any solution to this problem is appreciated.

Hello @Sreerup Banerjee

As mentioned by you, deleting "AppDesignerMainPanelLayout.json" file and restarting MATLAB is one of possible workaround to fix App Designer Component Library and Component Browser missing issue.

"AppDesignerMainPanelLayout.json" file is located in 'prefdir' path of MATLAB. To get default 'prefdir' path, simply write it as a command in MATLAB command prompt

prefdir

In case of MacOS, most probably 'prefdir' path is located at "~/Library/Application Support/MathWorks/MATLAB/<version>/preferences". This is hidden folder.
