Solver slowing down to basically having no progress (hyperelastic material, extreme deformation)

 

To my understanding, its the hyperelastic material deforming extremely at later stages of the step. and slowing the solver with no errors at all. Is there a way to somehow allow the hyperelastic material to deform further with ease? I wouldnt mind changing its material properties, i am analysing strains on the other parts (but unfortuntaly i need the hyperelastic gasket to stay)
