[2024.02.21-17.26.43:734][857]LogWindows: Error: appError called: Fatal error: [File:D:\build++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\Templates\Casts.cpp] [Line: 10]
Cast of Actor /Game/Castle.Castle:PersistentLevel.Actor_UAID_04421AF10E1219D701_1322753652 to MetaData failed

Unreal Engine Version 5.3.1 (original issue occurred)
Upgraded to 5.3.2 (upgrading didn’t fix)

What I know is my file started acting odd when trying to play with mesh/vertex paint for an object.

the world went dim with no change to lighting.

I closed out without saving and tried to open. I was able to load the project but not the level, Just kept getting the error above.

I’ve gotten a few different actor codes saying MetaData failed. They all seem to be attached to USD imported scenes.

I’ve tried to reload/reimport all materials as well as the USD files themselves. I even made a copy of the project, deleted all the USD files if somehow they are all corrupt.

nothing is working.

Not sure if I’m on the right path, if there’s any known issue with mesh/vertex painting USD assets? And is there any way to salvage this level data if I’m unable to load it?

Thank you in advance if you’re able to help.
