I believe this issue has been around before (aprox 2 years ago)

After clicking Play on Steam, the FFXIV launcher boots as normal, I log in using my account information and press Play on the launcher.
The game then boots into a black screen, and task manager will display FFXIV as 'Not responding', it will then crash without any error codes.

BUT....

If I edit 'steam_api64.dll' into anything else _after_ I've launched the launcher - the game will start as normal without issues.

This started happening again after the game got patched yesterday.
I'm glad the work around still works, but I'd like to report this issue regardless, because I'd like to play the game without constantly having to edit a filename...
