Hey,
I was having the same problem with similar error codes. Additionally i had a 100% crash at msq cutscene from the butcher's blood quest. Both of these problems appeared after i continued playing post Shadowbringers update. Before this i never had any crashing issues. Today i found a fix for the problem, but it might be a case specific fic. I hope it helps in at least someway.

PC specs: Gtx 1050 (laptop), i5 7300HQ, Win10

I had my FFXIV on my external SSD even before Shadowbringers and it worked fine, no crashing whatsoever. Something has happened to the game or my external drive, which led to the crashing issues. So the fix for me was just moving the game from external SSD to internal one (which was not pleasant as i didnt have any room there.) There can be few reasons why the game started crashing now. Either my external is breaking apart (cant test this as i dont have other external), USB speeds are not enough for this game anymore, or some files get corrupted between the transaction, which leads to crashes.

So if you have the game on external, try to move it to internal SSD. If not, this might not help you. Hope this gave some tips as where the issue might be.
