Strange figures in von-Mises stress scale.Can anyone please explain why the stress numbers are high?

In Ansys explicit dynamics, I see some strange figures in von-Mises stress scale. Can anyone please explain why the stress numbers are so high?

I am trying to create a model of a drill bit`s cone interaction with a rock. The following condition is given:

1. The rock is fixed from four sides. Shape - rectangular prism.

2. The cone moves towards the rock side with 20kN load and 80 rotation per minute. Remote displacement is set with 360 degrees of rotation and 5mm movement downwards

3. Simulation time is 4msec.

Result files are attached. I would appreciate any guidance regarding the figures or the problem in my simulation.

Thank you.
