Rear Gate Starts Closing then Opens Back Up

I have a 2021 Sienna and after having it about 6 months the rear gate started to have issues closing. It starts to close and goes down 2-3 inches, then beeps and opens back up. Nothing is in the way and I’m not standing too close. It will do it when I push the button on the gate, use my key fob or do it from inside the car. I’ve had it in the dealership at least four times and just get told they can’t figure out how to fix it. Sometimes I have to push it up to 20 times before it closes. I know forcing it will ruin the hydraulics but winter is coming and I live in ND. Any ideas or has anyone else experienced this? I will add that recently I was rear ended and had to have the whole rear door replaced. It still does it, so I imagine it has to be unrelated to the door itself🤷‍♀️

I'm sure already looked at:

Any loose weather stripping
Any metal or other small protrusion getting in way
Door square with hatch
Anything hampering the gate struts
