I solved it by going into XCode 15.2 Settings -> Platforms Remove the xrOS image that was still there and didn't mount anymore. Install visionOS 1.0

Thank you @DTS Engineer for this answer this sheds some light into an issue I encountered as well. As a follow up question. Is it somehow possible to have an object which is anchored the floor collide with an object which is anchored to a wall? As an example I apply an impulse to a ball which is anchored to the floor plane. The ball bounces off the floor plane towards a wall. When it hits an object that is anchored to the wall anchor it should trigger a collision event. Is this possible and if so how? Thank you so much for your support.
