Hello Greg, The demonstration above only loads a single model, but in my actual application, each scene has many models. Every time I switch scenes, there is a 2GB increase in memory usage, which can easily cause my application's process to be killed by the system. I hope the memory can be freed when removing models or when exiting the ImmersiveSpace. I have already submitted a feedback report: FB14959490. Best regards, Zohar

Before I close the immersive view, I had set it to nil. ------------------------code---------------------------- case .open: appModel.immersiveSpaceState = .inTransition appModel.root = nil await dismissImmersiveSpace()
