Unreal Engine Crashing

Hi. So I was learning how to create Quest System for my game and whenever I create SaveGame Blueprint called CharacterSave with Blueprint Structure called S_SavedQuest and implement the logic to them it starts crashing when I close engine and want to open it Again. If I delete those files in Content my project will open without any errors. I was looking in the Crash log and found weird things. It cannot find a Character Save blueprint. But how it cannot find when it is right THERE? And on top of that it cannot LOAD the S_SavedQuest. I can upload log here if someone want to go to bigger details.

Please help me I really do not know how to fix it :confused:

OK I found out that It must be the S_SavedQuest because when i Keep the CharacterSave there and only delete S_SavedQuest I can Run it and crash wont appear.

OK so I figured out that When I create in my Third Person Character variable for S_SavedQuest and close my Engine I cannot open it again because it just crashes. How the hell can one variable do that.
