Try this to see if it makes a difference for you;
Disable the steam overlay. Do this by right clicking on FF14 in your Steam Library, Properties then the first checkbox being "Enable the steam overlay" - uncheck it.
Then, navigate to whatever your drive is and find the FF14 folder: Program Files (x86)\Steam\steamapps\common\FINAL FANTASY XIV - A Realm Reborn/game
There should be two application files you can launch FF14 from (One being "ffxiv" and the other "ffxiv_dx11") right click on each one, properties, the compatibility tab, then at the very bottom should be a checkbox to disable full-screen optimizations. Check it on to disable them. Do this for both app files.

This weird crashing and "11000002" seems to be an issue people have been having since a newer patch and is springing up from out of nowhere, for some people there isn't a fix but for me I did the instructions above and it seems to have fixed it for some strange reason. I hope they address the issue properly though.
