Unable to run any MATLAB function and MATLAB errors on startup

All MATLAB functions, including restoredefaultpath, return an error of undefined function or variable.

Additionally, I see the following error on startup of MATLAB:

Error using eval
Undefined function 'workspacefunc' for arguments of type 'struct'.

Reinstalling MATLAB does not seem to fix the issue.

If you are unable to run the usual troubleshooting steps for a corrupted MATLAB path, the MATLABPATH environment variable may be corrupted.

Please check the value of the MATLABPATH environment variable by entering the following in the MATLAB Command Window:

>> !set

This will list all system environment variables present on your machine. The MATLABPATH environment variable should be unset, or set to

{MATLABROOT}/toolbox/local

You can find the full path to MATLABROOT by entering the following in the MATLAB Command Window:

>> matlabroot
