Already done above. The high G forces cause the blade tips to rub against the wall, creating friction that suddenly slows the fan rotation, disturbing the airflow, which leads to a compressor stall. Once the G forces disappear, everything back to normal. By the time the wheels hit, engines were already in G/A mode advancing to full thrust, the state most susceptible to a stall.
