Directx fatal error 1100002

[Vyi]

HELP, since the 10th of June, my game has been crashing with Directx fatal error (1100002). Seemingly came out of nowhere, crashes happen anywhere from basically launching the game to 10 mins or even a few hours, with no correlation on whats happening in game.

I have a:
GPU: RTX 2060 TUF gaming
CPU: Ryzen 5 2600
RAM: 32GB 3200Mhz Dual Channel
2 SSD's, one of which has windows, the other has steam and the game on it, an HDD
650 Watt PSU 80+
B450m motherboard

So far, I've tried:
clean reinstall
reinstall drivers
reinstall game, windows, programs
limit fps at 60
disable all overlays (like steam, nvidia and discord)
verify game files multiple times
take out ram and back in
take out gpu and back in
overclocking, underclocking GPU
uninstall rivatuner and Msi afterburner
disable full screen optimization on the ffxiv_dx11.exe file, after seeing it being recommended by a moderator here on the forum
change cpu priority for the game to high
Run system repair via cmd, which ultimately didnt find anything.
