Hello world crashes when creating swap chain. Access violation

I can't get these samples to run on my new laptop. I get a crash here at the call to CreateSwapChain: https://github.com/microsoft/DirectX-Graphics-Samples/blob/b5f92e2251ee83db4d4c795b3cba5d470c52eaf8/Samples/Desktop/D3D12HelloWorld/src/HelloTriangle/D3D12HelloTriangle.cpp#L94

The error message doesn't help me:

Exception thrown at 0x00007FFAEA06B3A7 (d3d12SDKLayers.dll) in D3D12HelloTriangle.exe: 0xC0000005: 
Access violation reading location 0x0000000000000000.

Any idea what that is? Or how I might debug it? I had sample code running on a Microsoft Surface, but when I tried this Asus Zenbook, this happens.

The stack trace in Visual Studio...

Start by reproducing the crash in Samples/Desktop/D3D12HelloWorld/src/HelloTriangle/D3D12HelloTriangle.cpp at line 94, using the Visual Studio stack trace and the provided machine difference as context. Compare the sample's behavior on the two laptops and inspect the CreateSwapChain call. Done means identifying a reproducible cause and documenting a confirmed fix or diagnostic explanation.
