Update: Over in the Unreal Slackers Discord, VictorLerp suggested that I add the newly released Vive OpenXR Plugin (v1.6.0 for UE5.1) to the project. With this plugin installed (along with Epic’s OpenXR plugin) I’m still getting the same assertion failed crash.
The Vive folks have also provided a sample UE5.1 project with their new v1.6.0 Vive OpenXR Plugin at the above link. It also crashes on play, but with a series of XR_ERROR_HANDLE_INVALID errors.
