WM crashes after finishing 8K build

I’ve been working on a world for some time, and I always built it using half or quarter resolution to speed up the process. I now decided to build it at full resolution (8K), and it went okay, however I accidentally changed a device before saving and this wiped out build. Since then, I’ve been unable to build my world at 8K again.

When building without conserve memory, the build usually halts after about 12 minutes, the program becomes unresponsive and CPU utilization falls to 0%. I have to terminate the process to exit the program.
I also tried building with conserve memory, which for the most part goes okay, however after the build finishes successfully, the program crashes without any chance to save the outputs.

Here’s the crash dump produced after the most recent post-build crash https://drive.google.com/open?id=1FP4K9ph6NxvCSyF6p0NGVEKyvYgsNPrK
After taking a look at the crash dump, the exception that causes the crash is “WorldMachine::FileAccessException at memory location 0x00000000003CCDF8”
