Why does Farming Simulator 25 hang at 90% on Zhitai TiPro9000?

Entering large farms was infuriating; the loading bar would just hang at 90% for seconds. I tried Windows Disk Defragmenter, but it did nothing and just added unnecessary wear to my drive. I used GamePP NVMe Queue Depth Configuration to set the write cache to 'Force Flush' and depth to 1024. CrystalDiskMark showed random reads recovered from 42-48MB/s to 65-72MB/s, and HWMonitor confirmed temps at 40-50℃. GamePP System Backup Tool measured read latency at 12-18ms.
