This is not a WASM only issue. It is also seen on desktop linux. See logs here: https://dev.azure.com/dnceng-public/public/_build/results?buildId=560509&view=logs&j=d25dc2c0-518b-5583-f661-5ac905106679&t=47cb0142-4d6b-5edf-a0a8-cf81fa3f7e05 @jkurdek Could you take a look, as your previous fix was to exclude Vector3 intrinsics from WASM.
