App wont publish

So I’m working on an app for a final project, and I’m new to Mendix. And I’ve got to a point where I want to test the app, but I get a check that just says “failed to build.” If anyone has ideas, please help! Edit: Also when I click on the publish button it says that my last update had consistency errors but I fixed those.

Go to Project -->Show project directory in explorer -->it will redirect you to project directory then select deployment folder and delete it → run your application again then a new build will be created.
