NDK compiling: error: unknown type name 'FCompositeNavModifier' ProcessResult.StdOut: FCompositeNavModifier Modifiers;

Hey!
I am trying to make a little fun game for mobile devices. I have not done much yet, but thought I could configure the android sdk in the project settings and maybe just package the game for android so I can see if it works or not. It came out to be not working and i honestly cannot figure out why. As far as i can tell it has to do something with this line in the error message:
ProcessResult.StdOut: E:/Program Files/Epic Games/UE_4.20/Engine/Source/Runtime/Engine/Classes\AI/Navigation/NavRelevantInterface.h(63,2): error: unknown type name ‘FCompositeNavModifier’
ProcessResult.StdOut: FCompositeNavModifier Modifiers;

But it is a file i never touched. So i created a new blank project and tried to package that one for android but i get the same error. I add the logfile to this post.
I compared my settings for the sdk with some i found on other topics.

Thank you very much in advance!
And sorry if it comes out to be a dumb thing…
