Nvidia Omniverse can not open exported open usd files from OpenUsd plugin

Hi. I know this might not be appropriate to ask in here. But I also ask the same question on NVIDIA end. I just want to know how other people approach this pipeline.

I exported the scene from unreal 5.6 into .usd format with the Unreal Engine’s openusd plugin https://dev.epicgames.com/documentation/en-us/unreal-engine/universal-scene-description-usd-in-unreal-engine?application_version=5.6.

However, when I want to open the exported .usd with Nivida Isaac Sim, I get an error like this:

2025-06-23 02:33:44 [1,619,316ms] [Error] [omni.usd] Failed to open : C:/Users/26328/OneDrive/Desktop/test/AssetZoo.usd
2025-06-23 02:33:44 [1,619,325ms] [Error] [omni.kit.window.file.file_window] Failed to open stage C:/Users/26328/OneDrive/Desktop/test/AssetZoo.usd: Failed to open:C:/Users/26328/OneDrive/Desktop/test/AssetZoo.usd

Please can anyone describe the correct pipeline of using exported scene from Unreal into Nvidia Omniverse with OpenUSD?

Great thanks.
