Maya data cannot be merged back into USD (with skeleton from UE5)

[an_nh1968]

I was very interested in USD and decided to apply it to my workflow between Maya and UE5. I discovered that Skeleton (UE5) keyframes when imported into the USD stage in Maya would not automatically change when I increased the Time Slider's Framerate (eg: 24 -> 48fps). My camera is created in Maya at 24fps starting from 0-70frames. After raising the Time Slider to 48fps, it will automatically add a key to become 0-140frames. I realized the Character and its skeleton wouldn't change like that in the USD stage, so I tried the "Edit as Maya Data" function and it was great to see that the keyframe automatically adjusted to the correct timeline. mine. But trouble happened again, when I clicked "Merge Maya Edits to Usd" an error occurred and I couldn't find a way out.

Below is the error line: 

Error: Given export root was neither a parent or child of any of the items to export; export aborting
# Error: RuntimeError: file <maya console> line 1: Error occurred during execution of MEL script
# file: C:/Program Files/Autodesk/MayaUSD/Maya2024/0.25.0/mayausd/MayaUSD/plugin/adsk/scripts/mayaUsdMenu.mel line 643: Given export root was neither a parent or child of any of the items to export; export aborting

Any help is appreciated.
