Cannot install add-ons in MATLAB R2023a on Linux

I wanted to install the new add-on for the new matlab desktop that would give me darkmode. Having experience with matlab previously I've installed it on my Linux system. Being Fedora 38 with 6.4.10 kernel but when I click on add-ons I get the following error message:

Error using matlab.internal.cef.webwindow
MATLABWindow application failed to launch. Unable to launch the MATLABWindow application. The exit code was: 127

Error in matlab.internal.webwindow/createImplementation (line 319)
                implObj = matlab.internal.cef.webwindow(varargin{:});

Error in matlab.internal.webwindow (line 163)
            obj.impl = obj.createImplementation(varargin{:});

Error in matlab.internal.addons.AddOnsWindow (line 41)
            obj.webwindow = matlab.internal.webwindow('about:blank', obj.debugPort);

Error in matlab.internal.addons.Explorer/createNewWindow (line 111)
                obj.addOnsWindowInstance = matlab.internal.addons.AddOnsWindow(obj.WINDOW_TITLE, clientType, obj.windowStateUtil.getPositionForExplorer);

Error in matlab.internal.addons.Explorer/show (line 61)
                obj.createNewWindow;

Error in matlab.internal.addons.launchers.showExplorer (line 140)
            matlab.internal.addons.Explorer.getInstance.show(navigationData);
            

I've tried reinstalling Matlab several times and try some solutions I could find such as giving the binary -x permissions.

As well, in my terminal running matlab doesn't work unless I'm in the correct directory.

$ sudo mv <matlabroot>/bin/glnxa64/libfreetype.so.6 <matlabroot>/bin/glnxa64/libfreetype.so.6.bak 

Worked!
