Sadly, welcome to the club. I have the exact same problem, and have been fighting with SE since Feb, with no resolution.

Nice job so for on the diags, some other things they may tell you to try, just to beat them to the punch.

- Disable full screen optimizations for the executable
- Check that the built in GPU is disabled (may not be possible since your on a laptop)
- Silly, but make sure the OS is fully updated
- Also silly, but try giving the ffxiv_dx11.exe a higher cpu priority through task manager (did squat for me, but they did ask)
- A very minor thing that got a very small amount of stability was to turn down/off the shadows and their quality.
- I see you have Steam and a few other loaders. If FF14 is not the team version, they will ask that you shut them all down.
- I don't know if it's still true, but Nahimic used to have a REALLLY bad rap, and wasn't good to have on a machine, but it may not be removable in your situation, and it shouldn't really affect FF14, just a side note.

I feel for you, as the crashes make it difficult to play, let alone enjoy the game now. I don't know if any of these will help, or give you more stability, but they are thing SE is likely to ask you to try. My read is that they have a problem with the game, no clue where it is, or are unwilling to admit it or address it. But that's me after 6+ weeks of trying to resolve it.

Good luck.
