Failure to load files falls through

err:   d3d9.dll loading failed: 126

Long story short I downloaded an rtx-remix debug build, and eventually I figured it wasn't working because I was missing the bunch of MSVC debug libraries needed by dxvk's d3d9 and usd_ms dlls.
But this took me longer to figure out than I'd have liked because the "Direct3D is not available due to an unknown error" dialog the game was throwing at me made me shift my attention to some whatever stupid specific incompatibility of its.

Not saying you should go the whole hog and plus with diagnosing, but something this dead fundamental should be given more notability.

err:   RegisterExitCallback() failed with error code 87

Sigh, meanwhile this happened when I accidentally deleted the .trex folder from the rtx-remix official package to replace it with the updated stuff from just the dxvk-remix repo (i.e. but completely forgetting that I was still missing the bridge's own NvRemixBridge.exe).

Nothing is particularly obvious from the outside, until you start to log the api calls preceding the silent crash.
