Random crashes during campaign - 64bit

[Blinx7882]

Trying to play through the campaign, all my crashes so far have been on the level Village, not sure if the level is part of the problem, some previous logs in the callstack state a memory access violation, the callstack pointing to CryRenderD3D10.dll

This latest crash, I added some launch commands to run in dx9 and I got the following error after completing the side objective in village for the radar station and the game saved, then crashed: "C1-Launcher Game v6 64-bit Access violation exception (0xC0000005) at 0x0000000030573ECC Write to 0x0000000036768689 failed" The callstack for this one seems to point towards "CryAction.dll"

I have an AMD system, Ryzen 5900x and a RX 6800 GPU - not sure if any of this is contributing
