Dynamic Scenario - Inertia Error in sub product

Hello,
i have a Product (with mechanism: axe rotation) with sub product (blue part + brown part, with mechanism: 1 free rotation).
Mass is define (see capture).
Kinematic simulation: OK
Dynamic Simulation: Error. seems to be impossible to calculate inertie in sub-product in new angle configuration.

Is it possible to do dynamic simulation with assembly of mechanism ?
Any solutions ?

Best Regards
