I suddenly got a strange unexpected error with the following messages:

ffxiv.exe+16E6F4
ffxiv.exe+1725A2
ffxiv.exe+171EDB
ffxiv.exe+171621
ffxiv.exe+16CB0F
ffxiv.exe+DB9AB5
KERNEL32.DLL+18484
ntdll.dll+63AB8

what's particularly strange as this is only happening to one of my alts. I tried logging onto different characters and they're fine, just not this one. Plus I could play as normal at first, it was when I completed the 2019 heavensturn quest, did I get the error, and now I can't login onto this character at all.

I tried searching for each error and I don't know if anybody has gotten them before? anyone have any idea?
