Pull the disconnect for the closer, and try opening and closing the door manually. Does it open and close smoothly at all points, and do the springs seem to be properly supporting the door? If not, it could be that the door is feeling some resistance, when trying to close (note that this can be affected by temperature extremes). In addition, you can try closing the door (with the door closer) from the inside, and watching both the door and the sensors carefully, to see if they change or have some problem during the closing process.

This would be my guess as well. There's adjustment possible where the little wheels in the track meet up with the door sections, if it's dragging against the frame too tightly. You want a reasonably tight fit for low airflow, especially if you've paid more for insulated door, but if you're just "scraping' it along the garage framing either side it might be sensing the added friction in some temperature and humidity conditions (depends what your framing is) and that's what's making it stop and reverse vs. fighting it.

Check the track alignment, keep an eye on the rollers and pins and see if they start pushing in at a certain point. If so, maybe loosen the bolts and adjust track to prevent the tightness.

THIS. Tune the door first. Also examine the spring. You’d be amazed at how many 2 spring doors have 1 broken spring.

Change those in pairs and unless you know what you are doing hire a pro.

Also lube the tracks really well with a good quality spray lubicant.
