all that happened before the game crashed was me shift-tabbing to chat to a friend with the in-game steam ui

Hello SparkyBoy and thank you for the report.
Have you done anything specific in game prior to the error message appearing? (for example, opened inventory, ate a consumable etc.)

I crashed again today, this time it was when i did nothing but lay down next to a tree the NWAF on the x64 bit launcher.

Hello SparkyBoy.
Was it a game crash with an error message or has this particular Virtual Machine Exception window showed up?

I wasn't able to see any error message, as the game made the crash sound then my screen went completely black. The only way for me to get out of the black screen was to press the escape key which took me back to the desktop, without any error message or virtual machine exception window.

Thank you SparkyBoy.
The fix i have mentioned was specifically for the Virtual Machine Exception error. We will analyse the crash logs you have provided to check for the cause of the crash you have experienced and will let you know here.
