I have purchased the Signal Processing Toolbox, but MATLAB still throws a "you need the Signal Processing Toolbox" error when I try to use the square function per the screenshot. I have tried reinstalling MATLAB and restarting the program.

I am not certain what the problem is.
imshow(imread('Screenshot 202....49.59 AM.png'))
First, run these from a script or your Command Window:
restoredefaultpath
rehash toolboxcache
.

Depending exactly how you install the toolbox, situations can arise where a toolbox is installed but the license is not updated.
Try Help -> Licensing -> Update Current licenses
