This error in your packaging log stands out to me:
ProcessResult.StdOut: LogProperty: Error: FStructProperty::Serialize Loading: Property 'StructProperty /Game/BP_MainSaveGame.BP_MainSaveGame_C:Items.Items'. Unknown structure.
ProcessResult.StdOut: LogClass: Warning: Property Items of Items has a struct type mismatch (tag FallbackStruct != prop ST_ItemData) in package: FObjectReader. If that struct got renamed, add an entry to ActiveStructRedirects.
Seems like taking a look at that Items struct might be a step forward.
its eaier to read if you screen cap so wee can see red
but this missing pin will hoop it:
ProcessResult.StdOut: LogOutputDevice: Error: Ensure condition failed: !FindPin(FFunctionEntryHelper::GetWorldContextPinName()) [File:D:/Build/++UE4/Sync/Engine/Source/Editor/BlueprintGraph/Private/K2Node_FunctionEntry.cpp] [Line: 364]
