Crown first, then aligners? Or aligners then crown?

I previously had braces in my teen years, but my teeth shifted a little making a very slight overbite. After my baces I had a root canal in my front tooth, over the years it has created a slight discoloring, you can't really tell unless you look at it carefully. I want to straighten my teeth again but I'm not sure if I should get a crown on my front tooth or straighten them first.
