Assembly of Parts

This is a simulation involving the assembly of four parts.
The assembly process involves fixing the bottom-most part in place and moving the top-most part by -2.6 mm in the y-direction. The goal is to determine the stress and strain for each part.
However, the calculation is not progressing at all.
Please advise on how to resolve this issue.
