Did you do a clean reinstall, i.e., where you completely erase the Matlab installation folder prior to reinstalling?
In any case, show us the result of,
whos -all saveobj

Hello Laura,
It seems like you have shadowed some built-in MATLAB functions with your own functions or scripts. This might be causing MATLAB to issue warnings about potential conflicts with the built-in functions.
Here are few suggestions to help resolve the issue:
Rename your custom scripts or functions to something unique names that doesn't conflict with the built-in function.Save the changes and restart MATLAB.
As Matt mentioned in the comment section, consider seeing what these commands ''which -all saveobj ","which -all set",etc return.
There is also a chance of MATLAB path being corrupt or else contains reference to a different MATLAB installation as well.
  • Start up the new MATLAB, and when you get a prompt, give the command "pathtool".
  • When it brings up the box listing the paths, go down to the lower right and click on 'Default'. Then click to Save the change. You can then cross-check by exiting MATLAB and starting it up again.
If the issue still persists, you can contact the MathWorks Technical Support.
Hope it helps.
