Basic Fitting tool not working

I tried fitting a graph to some data using the basic fitting tool option but recived the following errors:

Hey Ran,

You can try re-installing the 'Basic Fitting Tool'.

You could also try by deleting R2020a folder in C:\Users\ \AppData\Roaming\MathWorks\MATLAB - link, or refreshing the file system caches - link.

in case, none of the above options work, you should try re-installing MATLAB.
