While on final approach to Runway XXL approximately at 700 feet; the First Officer disconnected the autopilot to perform the landing. I heard the autopilot disconnect sound follow by a strong noise. The First Officer told me that the control column got 'stuck' momentarily and he pushed it forward and it got free (I was looking outside when it happened). We looked into the problem [and] everything was working normal. No CAS (Crew Alert System) indications; hydraulics were looking good and flight control page was good. The flight controls were moving correct and free. We continued with the landing.
I was PF (Pilot Flying) on the ILS XXL into ZZZ. At about 600 feet AGL I pressed the AP (Autopilot) disconnect and the AP disconnect warning sound came on as it always does for about 1-2 seconds. I had full roll control; however; I needed to force the control column forward to get pitch control. The control column was somewhat stuck in position. It made a light snapping noise that was loud enough to also grab the Captain's attention. I had full control after it and landed the plane safely. Neither I nor the Captain have experienced a similar issue before. On the ground we performed another flight control check before shutting down the engines and the EICAS (Engine Indicating and Crew Alerting System) Flight Control Page showed no malfunction. We called MX (Maintenance) and Dispatch to take care of the issue.
Flight crew reported the First Officer's control column stuck after auto pilot disconnect during landing. It became free after 1 to 2 seconds of force applied and the landing was continued.
