ANSYS Static Simulation Error - A solver pivot warning or error has been detected

Hi Everyone,

I'm working on ANSYS ACP - Static Simulation Carbon Fiber Wheel Rim but a message appear like this (Image 1):

"A solver pivot warning or error has been detected in the UX degree of freedom of node 1783 (Image 3) located in Surface Body. This is usually a result of an ill conditioned matrix possibly due to unreasonable material properties, an under constrained model, or contact related issues. Check results carefully. You may select the offending object and/or geometry via RMB on this warning in the Messages window."

I don't know where the problem is. If it's the geometry, I attach my geometry faces on (Image 2). I also display my boundary conditions on (Image 4). I used ACP Prepreg on this simulation.

Please help, I'm new on Ansys.
