Questions about the conduct of IAT experiments

OS : Win 11
PsychoPy version:2023.2.2
I’m trying to write an IAT experiment program using psychopy, but I’m having some difficulties.
When the stimulus picture is presented in time, it can be carried out smoothly when the button is pressed. However, when the stimulus disappears, there is no response, and the experiment cannot be continued, and the screen is empty, and the buttons do not respond.
Any help I would appreciate it.
