Hello !

I tried to link an image to the forum, but it seems it doesn't appear, so here it is, written :
ffxiv_dx11.exe+410B79
ffxiv_dx11.exe+40356A
ffxiv_dx11.exe+418319
ffxiv_dx11.exe+404B11
ffxiv_dx11.exe+40BC8E
ffxiv_dx11.exe+40C2C7
ffxiv_dx11.exe+40B86F
ffxiv_dx11.exe+40C452

Another error with different numbers after ffxiv_dx11.exe+ happened, but I don't have the numbers now, I'll play more to see if it happens again to give you those numbers.
I don't run anything related to FFXIV while playing. Sometimes Discord, sometimes nothing at all.
I only have one character.
I'm using HWMonitor and/or MSI Afterburner sometimes to check over heating, and it never happened.
This issue occured in full screen mode and in borderless mode.
I reinstalled the game on the C: drive.
I disabled OneDrive a few days ago, a bit after creating this post.

Here are all the steps I tried for now :
- Reinstall the game.
- Repair game with launcher.
- Uninstall and install GPU drivers.
- Install on another drive (C: to E:, then to C: again).
- RAM test (everything clear).
- Windows scan with cmd.
- Check for malware and virus.
- Underclocking and undervolting with MSI Afterburner, my GPU being MSI GeForce RTX 3070 Gaming Z Trio 8G LHR. This seems to help me play longer, but the error came back.

Thank you for your time.
