Trying to run computer vision toolbox matlab 9.11.0.1769968 (R2021b). Get the following error
>> handData = load('hand3d.mat');
Warning: Variable 'fixed' originally saved as a pointCloud cannot be instantiated
as an object and will be read in as a uint32.
Warning: Variable 'moving' originally saved as a pointCloud cannot be instantiated
as an object and will be read in as a uint32.

The pointCloud function is part of Computer Vision Toolbox and was introduced in release R2015a. Do you have this toolbox installed and licensed? You can check this by running the ver command and looking for a line starting with "Computer Vision Toolbox" in the displayed output.
If that line does not exist you will need to install Computer Vision Toolbox to use this function.

It sounds like your path may have been corrupted at some point. Try to restore the default path using restoredefaultpath.
