How to define a Contact analysis with Hyperelastic materials

I am simulating a scenario where 2 parts are touuching and one is made of a hyperelastic material, hence i can only run it contact.

- When I run it with 2 Output time steps (0-1), the solution converges (Single Pass) and I get some results.

- When i take the same run, and increase the output to 5 time steps, the solution always terminates because it fails to converge at a load factor less than 1.

Can someone pleasae help? How can the solution converge in the first case, but not in the second? Any guidance is appreciated. (If it helps, I also added a lot of mesh refinement points in he contact region and raan the 2nd analysis again and it still failed.)

Could you try to run it with 2 time steps, the load factor being the one that didn't converge ?

It will allow you to check if it is due to the multiple time steps or not.
