PC Launcher script error

In case anyone else has this issue:

My computer had crashed and I was getting this error when launching the PC version of the game:

An error has occurred on this page

Line: 1
Char: 1
Error: Invalid character
Code: 0
URL: https://launcher.finalfantasyxiv.com...35ba.bundle.js

There is a thread about this here:
https://forum.square-enix.com/ffxiv/threads/407863

I tried everything there but it didn't work. What worked was to open Internet Explorer 11 and I made it my default browser and then I went to Internet Options -> Reset Internet Explorer Settings -> Reset.

Once I restarted my computer the launcher started working again. Hopefully this helps someone else having this issue.

Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

As this issue has been resolved, we will be moving this thread to "Closed Concerns".

Good luck with your adventures through Eorzea!
