Game randomly freezes / crashes with no error message

[ToastedCheese]

I am on 5 days now with not a single freeze / crash. I can't say for certain what helped but here are a few things I did that I believe may have helped:

Starting with most important in my opinion:
-Go to your FFXIV game folder > right click on ffxiv_dx11 > Properties > Compatibility tab > enable (checkmark on) "Disable fullscreen optimizations".

Other things I did and how I run the game:
-Disabled Nvidia In-game overlay (in Nvidia GeForce Experience settings)
-Disabled Steam overlay (right click on game in Steam library > properties > general)
-Disabled Vsync as I have Gsync anyway, I cap the fps of the game in Nvidia control panel to 100 fps (you can set different cap like 60 if you want)
-I play the game on Full Screen mode
-In-game Graphics upscaling set to Nvidia DLSS with framerate threshold set to below 60 fps. I am aware that AMD FSR at 99 is sharper but I think the game attempting to make everything look so sharp even in distance might have caused crashes, if you want to use AMD FSR try at default 100
-All other graphical settings are at maximum

Greetings. I just tried the disabling of fullscreen optimizations, but sadly within a minute of reloading the game, standing at a retainer bell my game froze. So I suppose that isn't the solution in my case.
I have previously tried DLSS mode but it still froze with that as well
For the time being I've now disabled Steam and Nvidia overlays and limited my fps to 60. It hasn't even been an hour since trying this, so far it's not froze but it can happen at any time... I will try to update should that change or seemingly fix it

Edit: The day after posting this, the freezes happened again
