Can a Swashbuckler Rogue use sneak attack on an isolated target at OVER five feet(Ranged)?

There are a few questions SIMILAR to this that I’ve found on the website, but none cover this exact issue.

Can a Swashbuckler Rogue use their Rakish Audacity feature to sneak attack with a ranged weapon? Assuming there are no other enemies around either the Rogue or Target. The wording of the subclass feature implies no, but it’s too confusing to say for sure.
