Warning: Initializing MATLAB Graphics failed

I got the following error today when I restarted matlab and I am not sure how to fix it

Warning: Initializing MATLAB Graphics failed.

This indicates a potentially serious problem in your MATLAB setup, which should be resolved as soon as possible. Error detected was:

MATLAB:load:unableToReadMatFile

Unable to read MAT-file /home/nathanielgoldfarb/.matlab/R2021a/matlabprefs.mat. File might be corrupt.

> In hgrc (line 163)

In matlab.graphics.internal.initialize (line 15)
