Error during login/game patch update

Update disclaimer

• [X] Yes, I have checked and my issue is not related to the game updating and plugins not working correctly.

What did you do?

Just updated XIVLauncher and I've been trying to download the game patch files. Sometimes the error happens before I put my login credentials, sometimes I manage to "login" and start downloading the patch, then it happens and all windows are abruptely closed.

Try setting your Windows and XIVLauncher language to English. We're not sure why, but Portugese causes the launcher to break.
