My goal is to cross-compile a project to run on a GDX Spark.
I am using Unreal 5.6.1 on Windows 11 to package the project.
The project is the Vehicle example games project, with no changes.
When the packaged build is launched on the Spark it crashes with the following in the log:

Based on some searching for similar issues, it seems like there might be a Vulkan driver issue.
The installed configuration on the Spark is:
Driver Version: 580.126.09
CUDA Version: 13.0
To keep this test as clean as possible, the OS has just been reinstalled after a disk wipe, and no changes were made, other than updating through the DGX Dashboard.
I am not using remote desktop - just a directly connected HDMI monitor, USB-C keyboard and mouse.
Any suggestions on how to get this running would be appreciated!
