[unknown]: FINAL FANTASY XIV issue

[Xinxin0205]

Thank you for the reply. I try more details about my original post about the error.
The error happened on the new launch of the 5.15 client and I can't use Microsoft IME for Japanese typing and my Discord Overlay isn't working at all after the new client.
Game Capture when I tried to stream didn't work and I had to use Window Capture for the game.

Even tried run on compatilibity, run on admin and more didn't even work at all.

Could it be the client issue and since the ff14.exe has not recognized by my copy of Windows 10 after the 5.15 client update?
