I've had this problem on occasion with other Android phones before I got the Zenfone 6. If you want an immediate fix without waiting for Google to patch it, you can try uninstalling all Play Store updates in your System Settings < Apps and Notifications < See All Apps < Search "Google Play Store" < Menu (upper right corner) < Uninstall Updates.
From there, re-open the Play Store and attempt to update your apps again. Please also submit feedback to Google in the Play Store within the left slide menu on the bottom.
