[IMX8MP] DemoExperience GUI doesn't works on Yocto 4.0

OS: Yocto 4.0

Kernel: 5.15.71

As title, that strange when I compile image on my host side, boot up works but when I open NXP demo experience, it's emtpy... Even if I change to command line mode using 'demoexperience tui' commnad, also showing No demos. So I check something as following:

1. /home/root/.nxp-demo-experience/ is exist in my rootfs

2. Execute demo under /home/root/.nxp-demo-experience/ one by one, it works perfectly, for exmaple:

python3 /home/root/.nxp-demo-experience/scripts/machine_learning/MLDemoLauncher.py detect (works)

3. Use strace to check something wrong or not, but it seems no problem:

Hello,

Apparently is bad download of demoexperience since all this issue is due to your host, i suggest to erase everything and download and burn again to see what happen.

Regards
