But it’s old and even the founder abandoned it long ago around 2012.

Dries is still using Drupal. Here is his personal blog, where he discusses updating to Drupal 11: https://dri.es/drupal-11-released

Dries is the founder of Acquia, whose products are all based on or related to running Drupal websites.

Dries was the keynote speaker at DrupalCon Barcelona last month, where he discussed the new features currently under development in Drupal: https://www.youtube.com/watch?v=Wce6FkNN2Io

It was also a nightmare upgrading the versions of it.

This was an issue prior to version 8. All major versions since then have been directly upgradable. It usually takes me 2-3 hours to do a major version upgrade. Maybe a few more if there's a lot of custom code.

Similar to this, I don't think you should have the user sometimes click on the dialogue box (at the beginning) and sometimes click on others elements. I kept trying to push the mouse icon the first time I went through. Or, alternatively, you could make clicking the dialogue act the same as clicking the buttons. That way even if you do that, it works.
