Hi everyone,

I am facing an issue with my packaged game.
(It is working properly in the editor).

Each tile I try to open a scene with the given BP I got the following error:

"LowLevelFatalError [File:D:\build++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\Serialization\AsyncLoading2.cpp] [Line: 1648]
ObjectSerializationError: /Game/Glyphen/Characters/Enemies/Golem/BP_Golem (0xB59227765637F029) /Game/Glyphen/Characters/Enemies/Golem/BP_Golem (0xB59227765637F029) - BP_Golem_C /Game/Glyphen/Characters/Enemies/Golem/BP_Golem.Default__BP_Golem_C: Bad export index 1165623295/59.

Crash in runnable thread FAsyncLoadingThread"

Can anyone help me on this?

Regards

Hi, I met the same problem. If I resave this asset and rebuild, the other asset will report the same issue.
Did you find a way to reslove this?

Hi there,

On my side I solved this by deleting all build files (Build, DDC and intermediate folders) and then rebuild.

Just deleting Binaries seems to do the trick for me.
