As per the error message you are getting, it looks like you are facing rigid body motion. Can you check the initial contact information by inserting the contact tool and see if any contact status is near open or far open. If you have contact with some gap, try using a small contact stabilization factor(0.05 or 0.1) or change the interface treatment to 'Adjust to touch'. Also, check the below AIC course for more details on preventing rigid body motion.
