In Transient Structural, leave Large Deflection turned On.

Break the Transient Structural into two steps.  Step 1 raises the force to just below the value when the block will break free. Step 1 can have an End Time of 1 s and relatively large Initial and Maximum Time Steps of 0.1 s and a Minimum Time Step of 1e-5 s.

Step 2 has a slightly higher value of force that is above the break free value. Step 2 can have an end time of 1.1 s but it has a small Initial and Maximum Time Step of 1e-3 and a Minimum Time Step of 1e-5 s.
