USD Stage - Assert !EdgeArray[EdgeID].ConnectedPolygons.Contains(PolygonID)

One of Pixars example .usd files is crashing the editor when importing with 'USD Stage' (KitchenSet imports with no errors)

It is possible to import the file via content browser without crashing. (I only see one tiny building when importing this way)

Tested with 4.25 10303526 With different result - If I open the .usd and then 'Reload' the same file through 'USD Stage' it does not crash.

Without reloading - EXCEPTION_ACCESS_VIOLATION reading address 0xffffffff crash

1. Enable USD Importer Plugin
2. Download 'CitySet' from Pixars USD examples [Link Removed] (Also attached)
3. Open Window -> USD Stage, open+import downloaded USD (All default settings)

Result: Crash with !EdgeArray[EdgeID].ConnectedPolygons.Contains(PolygonID) assert

Assertion failed: !EdgeArray[EdgeID].ConnectedPolygons.Contains(PolygonID) [Link Removed] [Line: 571]
