I installed Xcode 15 beta 5 as well as the simulator, the iOS simulator runs very very slow, it takes nearly 30 mins to start the device, and after it's started, it's very lag, can anyone help?

When I use pencil or highlighter of PencilKit on debug, and write it quickly, it'll crash. But it's fine on release the error message: -[MTLDebugCommandBuffer lockPurgeableObjects]:2103: failed assertion `MTLResource 0x2816cd0a0 (label: (null)), referenced in cmd buffer 0x11a041400 (label: Live rendering command buffer) is in volatile or empty purgeable state at commit' is it a bug, or am I making something wrong?
