SQL And Drupal skips admin set up
You are asking a lot of questions at the same time, but I assume your main question is How to recover from this failed installation?

You are seeing an UnmetDependenciesException, which means Drupal requires stuff (has a dependency) that has not been loaded... So probably several system modules did not install properly.

That would also explain the behavior you are experiencing, your Drupal installation is broken...

Best would be to start over from scratch, remove all the files and the database tables and try again. Also verify if you have met all of the web server requirements (Drupal 7 &amp; 8).
