Unrecognized function or variable 'efmenu' error when opening a figure or app

When I open a figure or an app in MATLAB, I get an error saying:

Unrecognized function or variable 'efmenu'.


Error using matlab.graphics.internal.figfile.FigFile/read (line 31)

Error while evaluating Figure CreateFcn.


Error using load

Error using wfigmngr>createMenus (line 956)

Restoring my default path and rehashing my toolbox cache doesn't appear to help.

Please run the following command in their MATLAB command window:

set(0,'DefaultFigureCreateFcn','default')

This error may indicate that you have defined a custom CreateFcn, and this CreateFcn is now incompatible or out-of-date, causing errors when it is used.

To see if MATLAB is using a custom CreateFcn, run the following command:

get(0, 'DefaultFigureCreateFcn')

If the first command does not resolve the issue, check Add-Ons Manager to see if you have "EzyFit" installed, and if so, try uninstalling it, then restarting MATLAB.
