I am trying to reload a struct variable i am using to store data.

When running the load command it simply says:

Hello Nicholas,

This issue often arises when the .MAT file is corrupted. Here are a few suggestions to resolve it:

• Create a new .MAT file from the same data. This will remove any issues in the .MAT file, making it accessible in MATLAB.
• If the problem continues, try saving and loading the .MAT file with the version property set to 7.3, as shown below:

    save('filename.mat','-v7.3'); 
    load('filename.mat','-v7.3'); 

For more information about the version property of .MAT file, refer to this documentation: https://in.mathworks.com/help/releases/R2021b/matlab/ref/save.html#:~:text=version%20%E2%80%94%20MAT%2Dfile%20version .
