I have a problem, I don't know why the property inspector in GUI doesn't show anything, it's empty. I checked the other computer in my university lab and it was OK. and it's just my computer problem and can't solve it.

I have the same problem. I get the error:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at com.mathworks.page.plottool.propertyinspectormanager.PropertyInspectorManager$3.run(PropertyInspectorManager.java:203) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:311) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:756) at java.awt.EventQueue.access$500(EventQueue.java:97) at java.awt.EventQueue$3.run(EventQueue.java:709) at java.awt.EventQueue$3.run(EventQueue.java:703) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:80) at java.awt.EventQueue.dispatchEvent(EventQueue.java:726) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:201) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:116) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:105) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:101) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:93) at java.awt.EventDispatchThread.run(EventDispatchThread.java:82)
How can I fix it?

try the following:
h=plot([1 2],[3 4]);
inspect(h)
If your property inspector shows up properly, you have a problem with the GUI configuration. If it shows up empty, I think something did not install properly during the installation process.

Oh, God, yes, it is hard to understand, I tried to reinstall it, but result is still the same! Is it because of Catalina?

Same problem here on Fedora 31 with R2019b. When attempting to open the property inspector either through the gui or calling inspect on the plot handle, I get:

Following this, any attempt to open a property inspector (even of a different plot) presents an empty window.
