I actually just tried this on my own domain and although it enabled WebGPU it had another error, which was:
"Find an error initializing the WebGPU device Error: Cannot initialize runtime because of requested maxBufferSize exceeds limit. requested=1024MB, limit=256MB. This error may be caused by an older version of the browser (e.g. Chrome 112). You can try to upgrade your browser to Chrome 113 or later."
For sure, ChessProgramming.org is one of the best resources out there.
Wrote this just trying to be a bit more of a straightforward guide to how to really get started - hard to sort through how many strategies there are out there when building an engine :)
