Here ive attached my full log. Please reply. Urgent.
Always look for “LogProperty: Error”, in your case there is reference to structure that probably no longer exist or is somewhere else:
"UATHelper: Packaging (Windows (64-bit)): Cook: LogInit: Display: LogProperty: Error: UStructProperty::Serialize Loading: Property 'StructProperty /Game/Interactables/Weapons/BP_BaseWeapon.BP_BaseWeapon_C:WeaponInfo'. **Unknown structure**."
What helps in this situations is fixing redirectors in “content” folder or removing saved and intermediate.
