Randomly i keep getting this error message even when I havent made any adjustments to UI or Actionbars at all.

One or more of your client settings files, which include your hotbar settings, failed to save.

I am on a brand new PC, fresh Windows and XIV install. So I wonder why I get this message now, when I have not ever seen this happen before on my 11 years of playing this game. I have had 2 PCs in the game's lifespan so far.
