Packaging failed after upgrading VR project from UE5.3.2 to 5.4.4

I encountered the exact same issue. It seemed to be something wrong with the steamVR OpenXR runtime that was causing it for me. Switching the openXR runtime back to the oculus one fixed it and allowed me to build without issue. I used this handy tool to switch between the two runtimes as needed. Best of luck!
