Flickering issue in App for Oculus Quest 3 with Passthrough enabled

Hello, I used one model which vertices around 400K and which is flickering and app is hanging on starting in Oculus Quest 3 and Passthrough enabled but when I am using another model around 300k which is not flickering so it's only vertices issue of the model or it may be other issue? I am using Unity Editor version 2022.3.24f1 and using Meta All in One SDK. I want to use 400k vertices model without flickering in Oculus Quest 3
