Why ctrl-c cannot force Psychtoolbox quit?

after run the programming, if i want to force quit the psychtoolbox and press ctrl-C, the process will not stop without any response. And if I press Tab+Alt or Win button to force to close the window, the Matlab will crash and directly close itself, but I just want to close the window opened by Psychtoolbox.

My old PC will not happen this problem with above operation.(R2019b) But if i make such operation in my new PC(R2021a), the crash must happen.

Pressing the Windows key let Matlab crash? This should not happen. Which version of the PsychToolbox are you running?
