The compression simulation, and the material "exploded" during simulation, why?

I am just using Comsol to simulate the process of compressing PMMA with the indented shape.
I followed the similar example from the Comsol examples, and set the PMMA as a viscoelastic material instead of hyperelastic material. But during the simulation process, the material began to 'explode' instead of being compressed.
The simulation is stationary, parametric sweep in time to simulate the compressing process on different moments.
So I am wondering what is the reason for this failure.
Is it because of the material setting? Boundary setting? Solver setting? Or others? Thanks a lot!
I posted the compressing processes on different time:
