Error when I try to quick launch my project

Hello there,

I need help. For some reason, whenever I try to quick launch my project in Unreal Engine 5.3.2, I get this error:

You may have to build the UE project with your IDE. Alternatively, build using UnrealBuildTool with the commandline:
UnrealGame <Platform> <Configuration>

Can someone please help me? Thank you.

(Now you may wonder why is this topic in the Blueprint section, well that because of a couple of reasons. One, this project is a blueprint project and two, there is no other place to put this topic in)
