GPURayTracingAccelerationContainerFlag is not defined

I run this project on win10, and I installed the Windows 452.28 vulkan beta driver, I got this error.

I ran this project on Win10 with a 3070ti GPU and node/npm installed from the Windows Node LTS [14.17.3] installer on the nodejs.org website..
I did not install the vulkan driver, instead I altered index.mjs so that GPU.requestAdapter had preferredBackend: "D3D12".
I got a blank window for about 3 seconds, then it closed and the console printed this same error:
