Gulp stopped running?

Question

gulp.js

Tell me how to solve the problem, I'm a beginner developer, I can't understand what's the matter...
Running 'default'...
[16:22:14] Using gulpfile ~\Desktop\Armata Time\gulpfile.js
[16:22:14] Starting 'styles'...
[16:22:14] Starting 'scripts'...
[16:22:14] Starting 'watch'...
[16:22:14] Finished 'watch' after 62 ms
[ 16:22:14] Finished 'scripts' after 231 ms

gulp.task('default', ['browser-sync', 'watch']);
It's probably sequential.
But neither browser-sync nor watch returns a stream, nor does it execute the done function.
In my opinion, you need to either run browser-sync and watch in parallel, or redo:

gulp.task('browser-sync', ['styles', 'scripts'], function(done) {
  browserSync.init({
   server: {
     baseDir: "./app"
   },
   notify: false
  });

  done();
});

gulp.task('watch', function (done) {
  gulp.watch('sass/*.sass', ['styles']);
  gulp.watch('app/libs/**/*.js', ['scripts']);
  gulp.watch('app/js/*.js').on("change", browserSync.reload);
  gulp.watch('app/*.html').on('change', browserSync.reload);

  done();
});

Try to see what falls and why. Hang an error handler on your tasks and look at the output.
