My fiance is also having the same problem. She is also a viera and has emailed Square Enix support about receiving the same CE-34878-0 error. She is on PS4 and has tried reinstalling the full game and making sure her PS4 is set as the primary PS4 as per SE and PlayStation support's request but still to no avail. Seems to only be a problem with the viera race and is only happening on PS4 and the error only occurs on FFXIV. This has been only occurring since Shadowbringer's early access was released and has not been properly looked into thus making the game practically unplayable as a viera on PS4. It impossible to make use of a fantasia she has paid money for because the game keeps crashing.
