I'm running R2022a on Mac OS V11.4. This symptom is very repeatable. It goes like this.

I start Matlab
I plot something
I close the figure with the Close button (the X)
I get the spinning wheel and Matlab is no longer responsive, has to be shut down. The spinning wheel never stops, I never am able to type in the command window again after that.

I just did the experiment with closing the figure with delete(). That worked fine. Then I tried again with the close button, and the wheel is spinning again.

Has anyone else seen this and do you have any idea what the cause might be?

I'm having the same issue. I think the one answer below isn't understanding the problem correctly–– Matlab is actually able to plot just fine. It breaks only upon hitting the 'X' to close the figure. And, at least for me, it doesn't do this with every figure, but I have no idea why it happens when it does–– the data is fine, and it's not a really huge plot or anything. If instead of clicking the 'X' you just type 'close all' in the command line, it doesn't crash.

Happens for me too. I'm on a mac and it's fine when I press apple-w, but not when I press the red cross or programmatically run 'close(fh)'.

Hello Randall Poe,

As per my understanding, as soon as you start working in MATLAB, it launches successfully; however, when you attempt to create plots, the MATLAB window freezes, displaying no content, and necessitating a force quit.

To solve this issue, you can try out one of the following things:

You can start MATLAB through the terminal via

/Applications/MATLAB_R2019b.app/bin/matlab

But the real problem solver is to give it full disk access. Please note that you can add MATLAB under System Preferences --> Security & Privacy --> Privacy --> Full Disk Access. Or, if MATLAB isn't listed, click on the + and look for it in the Application folder and add it to the list manually.

Another reason could be a recurring issue with Accessibility Options. It is possible that another application is using Accessibility features which are causing this issue. Please refer to the following MATLAB Answers link and navigate to Jon Gotow's answer where he describes how to check what applications use the Accessibility api.

I hope it helps!
