FAILURE: Build failed with an exception.

Only seems to happen with androidx.constraintlayout:constraintlayout:2.2.0
When I downgrade to version 2.1.4, the layout inflates as expected. ConstraintLayout itself always inflates fine.

Steps to Reproduce
Try to do a test run that inflates any androidx.constraintlayout.motion.widget.MotionLayout layout, using andoridx constraintlayout version 2.2.0

Expected behavior
NullPointerException should not happen, layout should inflate
