Everything was working smoothly but after update of Android Stdio 3.6 & Gradle to 3.5.0, Project is not building, Getting bellow errors

Here is gradle.properties
org.gradle.jvmargs=-Xmx4608m
android.enableJetifier=true
android.useAndroidX=true
Finally..
I have solved the problem..
I observed error was in constraintlayout as per logcat and observed the constraintlayout version which was alpha
I downgrade the version to implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
and the issue got fixed.
