Sounds like the sensor has moved and needs to be readjusted, the wire going to it might have come loose or the circuit board that controls this function is not working.
There are several garage door places around, having not used one I don’t know who is good bad or indifferent. I’ve always installed and adjusted my own.

If either one of the safety sensors is out of adjustment the door shouldn't work at all because the circut is open.
