I am on M1, Big Sur 11.3 and 2021a. Using run from editor is really slow and often matlab freezes when I run the editor. In general, the editor is very very slow. I see the same thing on my intel mac too (2021a, Big Sur 11.2).
Any help regarding this would be greatly apreciated.
Thanks.

Based on Walter Roberson's answer, making a new desktop alias to the MATLAB executable has worked for me so far:
  1. Open Terminal.
  2. Enter this command: open /Applications/MATLAB_R2021a.app/Contents/MacOS/
  3. In the folder that opened, control-click the MATLAB file and choose Make Alias.
  4. Drag the new alias to your desktop.
  5. From now on, to launch MATLAB, double-click your new alias.
My config:
macOS Big Sur
Version 11.5
Mac mini (M1, 2020)
Chip Apple M1
MATLAB R2021a, downloaded Aug 14, 2021

Thank you! This was driving me crazy. MATLAB R2021b wasn't exactly freezing on me but it was unusable. This is at least a band-aid on the problem.

Just updated to r2022b and this continues to be a problem (MATLAB extremely slow to the point of being unusable when opened using the Launcher). Was hoping they would have fixed this in the new version, but alas...

From my understanding for you MATLAB is freezing on Big Sur 11.3. This might be due the simultaneous launching of MATLAB Editor at startup. These troubleshooting steps might help you to solve the issue.
1) Initiate MATLAB with -nodesktop flag
2) Run the commands:
>> s = settings;
>> s.matlab.editor.InitializeAtStartup.PersonalValue = 0;
3) Quit -nodesktop MATLAB and launch desktop MATLAB.

Problem for me happens when I create figures in my script and then click on the close button after the script is done. This is really debilitating.

I updated to Big Sur 11.6 and Matlab 2021a Update 5 is running more stable than before.

I did the same and things seems to be okay.

I've got Big Sur 11.6 and just updated to r2022b and MATLAB is still slow to the point of being useless
