Cannot Save as on MacOSX

I cannot use Save As to save any document. I have full permissions for the folders I am saving in and can use save.

Save works, but save as a copy does not. The first time I try save as I get a flurry of errors starting with:

'java.lang.NullPointerException

at sun.reflect.UnsafeFieldAccessorImpl.ensureObj(UnsafeFieldAccessorImpl.java:57)

at sun.reflect.UnsafeObjectFieldAccessorImpl.get(UnsafeObjectFieldAccessorImpl.java:36)

at java.lang.reflect.Field.get(Field.java:393)

at sun.lwawt.macosx.CAccessibility.getAccessibleRoleFor(CAccessibility.java:248)

at sun.lwawt.macosx.CAccessibility$12.call(CAccessibility.java:263)

at sun.lwawt.macosx.CAccessibility$12.call(CAccessibility.java:260)'

My suspicion is that Matlab is not asking for the correct rights for the save window, somehow. I am running 10.15.7 and 2018b.

In my understanding, the above error is related to "Accessibility", which is also known as "Universal Access" for MAC. You can find this setting in Apple menu -> System preferences -> Universal Access. There is an issue with third-party applications on MAC that interferes with Java's accessibility code.

The workaround for this issue is to completely disable Accessibility ("Universal Access") in your MAC, reboot your computer and restart MATLAB afterwards.
