Blueprint Function Library has errors during creation

Whenever I try to build a Blueprint Function Library, there are compilation errors. Specifically:

CompilerResultsLog: Info ERROR: 'C:/Users/Username/Documents/Unreal Projects/Quest/Projectname/Intermediate/Build/Win64/UE4Editor/Inc/Projectname/BPTest.generated.h': Changes to generated code are not allowed - conflicts written to 'C:/Users/Username/Documents/Unreal Projects/Quest/Projectname/Intermediate/Build/Win64/UE4Editor/Inc/Projectname/BPTest.generated.h.confl ict'

`CompilerResultsLog:Error: Error Error: Failed to generate code for GQ_NENEditor - error code: OtherCompilationError (5)``

The file was just created, and I haven’t even had a chance to edit it, so I don’t get why it thinks the generated code has been edited.
