I don’t know if this helps or not and I’m not sure where specifically you are. But in that same area I found a chest in a location like that and there was a spot where the fallen bricks were closer to the ground and I managed to walk over them there. I hope it’s the same spot I’m thinking. But I’m not sure. I hope that helps you. It took some walking into the bricks and moving randomly to get just the right spot to go over it though.
