Matalb 2021a uses 100% CPU and is running very slowly

Hello,

I haven't used Matlab in the few months on my Mac OS ver 10.14.6, and not sure what happened but Matlab R2021a runs very slowly and uses 100% CPU. I've already updated R2021a with the update patch. Made sure Editor doesn't start with the start of MATLAB. There are no viruses, as far as I know. Starting it up using Terminal does not solve the problem.
