Whenever I add blocks in Simulink or Simscape using the quick add menu, the whole app freezes for a couple seconds

Hi, I am on a Macbook Pro running M1 Apple Silicon and MacOS Monterey 12.1. Whenever I double click on the Simulink or Simscape enviroment to quick add, the app works fine. However, the second I get past 1 or 2 letters the entire app freezes and I get a spinning wheel of death for about 4 seconds, then it works.

Its incredibly disruptive for the app to freeze every time I want to add anything to my model.

Has anyone encounterd this issue?

Same for me! Running on M1 Pro and Simulink freezes after typing a couple of letters. In the Apple Silicon Open Beta it is better, but I still experience a time lag. So not perfect either

Edit: I don't use any window managment software like Magnet etc. btw.

It is my understanding that you experience a lag while using Quick Add feature in Simulink/Simscape while using it on MacOS.

As per my understanding, a possible cause for this issue could be the use of Magnet which is a window management software for Mac. Turning it off may help in resolving the issue.

You can choose to ignore the current application from the menu bar icon of Magnet. Choose "Ignore MATLAB" to disable Magnet for MATLAB.

You can also refer to MATLAB answers link below which contains workarounds for various lagging issues due to incompatibility of Magnet App, BetterTouchTool or similar window snapping tools on MacOS.
