unreal crash after reimporting datasmith

[MonteithVDC]

Unreal Engine 5 is crashing when I try to reimport datasmith file. I have reimported the datasmith file at least 20 times already, but now it is crushing everytime I try it,

Fatal error: [File:D:\build++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\Obj.cpp] [Line: 300]

this is the error that I get. Somebody please help, this is the second time I am starting all over my Project because I had this error before too,
Thank you very much!
