Hello, thank you for helping.

For changes, there was a recent windows update I believe, back on 10th of June.

1) Checked, hardware was not overheating, neither did I perform any overlocks, fans are not obstructed.
2) Tried running without any of them running, nothing changed. No configurations using graphics driver-level programs were made.
3) I don't use any mods and/or injectors in the game nor do I have them in my system.
4) Tried, no changes.
5) Removed everything but my keyboard and mouse, nothing changed.
6) Updated and reinstalled yes
7) This too

Took awhile to try them all out, but no, it still crashes whenever I enter the Gyr Abania region, no issue with other Stormblood content like Kugane/Tamamizu/Doman Enclave. But at least now after the "Could not locate data files. Please reinstall FINAL FANTASY XIV.(1ffff)" window pops up, I can still talk in chat with my FC and party, it is just my HUD over a blackscreen, HUD can be interacted with, but it will not open any new windows(IE: pressing C or clicking [Character > Character] will not cause the Character window to pop up. But once I exit from this particular instance of the game and enter it again, I will crash in the loading screen like previously.

Are there any other suggestions?
