Unable to cook package for platform because it is unable to be loaded

I have spent the last week trying to package my game for playtesting, and when playing the game in the UE4 editor I run into no errors/problems.

When I package the game I get the following error

PackagingResults: Error: Unable to cook package for platform because it is unable to be loaded: C:/Users/Harry/Desktop/Uni Work/GoneRogue21/GoneRogue21/Saved/Cooked/WindowsNoEditor/MyProject5/Content/TopDownBP/Blueprints/RPSTrigger3.uasset

I have no idea how to solve this and have tried every solution I can find. The actor blueprint in question is definitely in the content folder, but UE4 seems unwilling to acknowledge it

Any Help appreciated, thanks
