Reproduction steps:
- Open XCode on a macOS Apple Silicon machine (M1 or later)
- In the Menu bar, choose Debug -> Debug Executable
- Choose the attached “Autobuild.app” as the executable to debug
- Start the executable (Button with play symbol)
- Wait for the App to start
- Open the in-game terminal (F1) (If it is not already open)
- type “preview level_01” and hit enter
- Wait for the level to load, after another short wait the App will close out with an assertion
- Observe the XCode console window
Actual result: An assertion is shown: “-[MTLDebugRenderCommandEncoder validateCommonDrawErrors:]:5970: failed assertion `Draw Errors Validation Vertex Function(xlatMtlMain): argument UnityInstancingDOTS_InstanceVisibility[0] from Buffer(1) with offset(4190720) and length(4194304) has space for 3584 bytes, but argument has a length(4096).'“
Expected result: The App does not assert and therefore does not close
