Why does Farming Simulator 25 freeze at 90% loading on Zhitai SSD?

I was devastated when saving large farm data; the loading screen would freeze at 90% as speeds dropped from 7000MB/s to 1200MB/s per CrystalDiskMark. I tried disabling the write cache in the system, but loading times actually increased by 3 seconds. I then used the GamePP NVMe Queue Depth configuration to increase the depth to 2048 and enabled the forced write cache flush. 4K random reads improved to 75-82MB/s per CrystalDiskMark, and SSD temperature stabilized at 46-52℃ per HWMonitor.
