I have been having this issue lately where I get this error when trying to launch FF.

I have followed a few reddit suggestions changing IE's settings and a lodestone report and so far nothing has changed. To get on the game I either have to spam click it and pray to RNGesus or restart and spam again. Sometimes the launcher is just black. Let me know if there is any way to fix this. ;-;
