Zuk Z2 loses settings after reboot

I have my Zuk Z2 since one year and everything just worked out fine.
But since 3 days I am facing a issue after every reboot, my Zuk Z2 with Zui 3.5.389 ST and Android 8.0 resets its settings.
It's not like a factory reset, but it resets language to chinese, time to am and pm instead of 24 hour format, doesn't show the battery percentage anymore and more little thing like the U touch settings are gone too.

Can anybody help me how to fix it?
I already tried to uninstall the apps which I installed some weeks ago but nothing helped.

Thanks for your help.
