Only black screen appeared

Hello! 

I built an AR application with Unity and Vuforia a month ago. And the app run well for some days. 

But after about a month,

when I open the app, only black screen appeared.(I didn't edit anything. I just have used the app.)

 

 

So, I tried the reason and I found it. After ARCore update of my devices, it is not working. 

Vuforia Ground plane and new version of Android ARCore cause the problem.

How can I solve this problem? Please help me.
