Hey Venat, you may want to re-install FFXIV, as it could just be corrupt data somewhere in your character file on your computer.

Or it could be that your character is now in Limbo like so many others. (See the Garuda-Limbo threads.) This is probably the worst-case scenario.

...or maybe a combination of the 2?

Have you visited the spot your Venat is stuck at on another of your characters? Maybe successfully loading the data on another character could resolve the issue?
