Garage Door Closes and Stops a Few Feet From Bottom. Then Falls Down.

See video below. It stops a few feet from the bottom then falls the rest of the way. Opener starts clicking. Red dot laser never blinks, so it's not an interference issue. Only does it maybe 50% of the time. Opens fine.

I did notice the chain was very loose so I tightened that up. Still didn't fix it. Any ideas?

look for a worn gear or broken tooth on the gear at the head unit. It will continue to get worse.

run the door manually by hand and see if it is catching... run the opener without the door attached and see if it catches
