Falling back D3D11 in build with error: d3d12: failed to create D3D12 device (0x887e0003)

I’m using editor version 6000.0.31f1. I have Direct3D12 as my primary graphics api with Direct3D11 as a secondary. D3D12 works fine in the editor. However, when I do a build, it falls back to 11 with the following error:

GfxDevice: creating device client; kGfxThreadingModeSplitJobs
d3d12: failed to create D3D12 device (0x887e0003).

A new empty project initialized D3D12 just fine, so I figure the problem lies somewhere my project. However, I’m unsure how to proceed narrowing down what exactly what might causing the issue.

I’m slowly adding assets to the new project and rebuilding to try to get it to fail, but any ideas on a better way to debug this?

Thanks!
