[00:48:25] The following tasks did not complete: watchFiles, browserSync, html, css, images
[00:48:25] Did you forget to signal async completion?

Answer 1

When you create a task, you must either return it through returnthe final execution, or through a call to the passed function. In your task browserSync, for example, there is a passed function done, but you do not return either it or returnthe result of the execution.
This is the first thing I saw, maybe there are still such errors. To avoid them, read the gulp documentation.
