Dell Venue 10 7000 Apps crashing after root

Hi ,

I tried the root of my Old Tab by using the Laptop software called Kingo Root. Unfortunately, I had some issues like Apps crashing each and every time when I am using for 1-2 minuet. I tried to download some apps from apkproz because of Google Playstore was not working in my Tab. I found that some apps downloaded from other stores was working good.

Is there any other way to handle this problem?
