Garage Door will go down, but not up.

Hey, so Ive never encountered this issue before. I checked for obstacles in the way of the sensors. Nothing. Sensor colors are yellow and green respectively.

When my garage door is down and I press the button the chain in the middle won't move. I feel like there is some mechanism preventing it from coming back up.

Any advice would be greatly appreciated!
