Can't open "aditof-demo 3.1.0"

Hello,

I try to use Raspberry Pi 4B to operate the LiDAR(AD-FXTOF1-EBZ). I have followed all the steps on the website called "Raspberry Pi User Guide". 

Unfortunately, I can't open it. When I pressed the play button, it would stop like the figure shown below.

When I used command window to open it, it showed some error message:

 I need some feedback to help me solve this problem.
