Launcher not working

[Norohanta]

Hello, since the maintenance, I've been getting multiple script errors when launching the game from Steam, and the launcher won't load.
All I see is a frozen Final Fantasy 14 screen with 18 script errors.
Here's an example: "https://launcher.finalfantasyxiv.com/v600/polyfill~d939e436-6e65987351d614033b8f.bundle.js"
I'd like to point out that the "6e65987351d614033b8f.bundle.js" part is consistent. The code in between that part and polyfill, on the other hand, is always different.
I've uninstalled and reinstalled the game multiple times since, but nothing has changed.
Due to this issue, I have yet to link my steam account to my FF14 account, as it requires the launcher, which does not work.
I also tried verifying the files on Steam, clearing cache and cookies, and following the steps for configuring internet options to resolve a similar issue with a different bundle number I saw on the forum, but it didn't work.
I tried running the game from the boot.exe file too, and the launcher appears, but when I log in, it says I don't have a license. But I suppose that's to be expected given that I'll be launching it on Steam.
I still have until March 20th before my subscription expires, and this launcher issue is costing me both time and money. I have also yet to receive a response to my ticket.
Please kindly help me in resolving this launcher issue. Thank you very much.
