Why is MATLAB slow after updating my MacOS to version 11.4?

After updating my MacOS to 11.4, MATLAB takes a long time to start or starts extremely slow. 

When using MATLAB it also sometimes freezes.

How can I resolve this issue?

This issue has been resolved with MacOS 12 Monterey

If you are unable to update to MacOS 12 and are experiencing slow MATLAB Start up, you may start MATLAB through the terminal as a work around.

To open MATLAB from the terminal, open a Terminal window (/Applications/Utilities/Terminal.app) and run the following command:

$MATLAB/bin/matlab

Where $MATLAB is the path to your MATLAB directory. For example, if you are using MATLAB R2021a and have installed MATLAB in the default directory, the command will be:

/Applications/MATLAB_R2021a.app/bin/matlab

Note: The issue does not seem specific to M1 chips, as it has been reported on Intel.
