Does your project folder have any non-english letters in it?
This is the usual cause of failed compiles.

Are you using an engine version compiled from source?
Does your engine intermediate/build/buildrules folder look like this?

build_pdb

If you are using the normal binary version of the engine try verifying it through the epic launcher.

Try running your IDE as administrator and see if that changes the needed permissions.
