How it happened
I’m not sure exactly why this is happening but since it’s showing FDataTable_Struct which is a struct meant to get references to data tables (Note: these Data tables were imported CSV files), this is done by using loadobject<>() can i not use loadobject<>() to get references to data tables(Note: i use loadobject<>() many times to get references to many data table ) this is done in the struct’s constructor, is this cause by trying to load to many objects?

Example of how i use loadobject
in .h
class UDataTable* DT;

in .cpp
FDataTable_Struct(){

DT = LoadObject<UDataTable>(NULL, TEXT("/Game/Path/EX_DATATABLE"), NULL, LOAD_None, NULL);

}

I would appreciate any help you could offer
