How do I keep datatables from being corrupted?

Development Programming & Scripting

(Unreal 5.1) Whenever I import DataTables from CSV (using a row structure from C++ USTRUCT(BlueprintType) that inherits from FTableRowBase), everything works fine, but then if I close Unreal and open it again, then the DataTables get corrupted, when I open it gives an error “Failed to load assets” and log shows “LogAssetEditorSubsystem: Error: Opening Asset editor failed because of null asset”). Any way to fix this/prevent this?

I’ve resolved this myself. The problem was in accessing datatables too early. I wrapped all datatable access with if (GetWorld()) and that solved the issue

Hi can you expand on this answer? Where did you add that check?
I’m having the same problem with a CommonMappingContextMetadata datatable
