Student Error on Statup

I have a student running the 2018B Student version on a Mac. On startup she gets the error:

Error in internal.hotplug.EventSource/stop (line 69)
      obj.Channel.close();
Error in internal.hotplug.EventSource/delete (line 53)
   stop(obj);
Error in internal.hotplug.EventSource (line 34)
    function obj = EventSource()
Eror in internal.deviceplugindetection.Manager (line 173)
   obj.USBDectorObject = internal.hotplug.EventSource();
Error in internal.deviceplugindetection.Manager.getInstance (line 246)
    devicePlugInManagerInstance = 
    internal.deviceplugindetection.Manager();
Error in matlabrc (line 86)
   pl=internal.deviceplugindection.Manager.getInstance(line 246);

Is there any red or orange text displayed before the first line of that message? If so show the full text as those previous lines may include information critical in determining the cause of the error.

Bump. Anyone suggestions? Thanks

I am seeing a similar error in a fresh install of Matlab R2023b Update 11 on an Oracle Linux 9 machine, but it is not present on two other Oracle Linux 9 machines. All three were installed with the same installer on the same day. All three are launching the same project.
