Raspberry PI - default project not starting

I downloaded and ran the latest V12.0.61.u5 PI image on a Raspberry PI Model B Plus Rev 1.2 and the default “myapp” is not starting properly. Below is output from /var/log/syslog. Any advice?

Jun 17 13:45:19 raspberrypi systemd[1]: Stopped D2000 Application ‘myapp’.
Jun 17 13:45:19 raspberrypi systemd[1]: Started D2000 Application ‘myapp’.

Hello,
are you trying to use D2000 on Raspberry PI 1? I’m afraid D2000 is compiled to work with RPI models 2 and above. We actually test it with RPI 3 and RPI 4 only.

I tried the image on RPI4, but the device does not boot. A fresh rasbian image on the same card does.
