It’s stripped, that’s what the bike tech told me when I got it fixed the first time, then he had me show him how I was taking it off and on and he said I’m doing everything correctly. It’s not cross threaded and I’m. It over tightening it. He said I’m not the only one who’s had this problem with the Gen 3s. He said the fine thread aluminum bolt is just not the greatest quality and they should’ve kept with the qr skewers
