Android app crash at start because of error "Unable to get provider androidx.core.content.FileProvider"

Upgraded Unity project from **2020.1.6** to **2020.3.4.** . Builds perfectly but android app crash immediately at start(tested on android 8,10,11) because of error **"Unable to get provider androidx.core.content.FileProvider"** App is not even getting to permission phase (photo camera, access to storage). How do i resolve this problem? Using in project Vuforia, NatSuite, and my own writen native android *.arr plugins to check android volume.
