After update of Android Studio 3.6 & Gradle to 3.5.0 unable to run project

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.

Try changing in gradle.properties

org.gradle.jvmargs=-Xmx4096m
