Why does Total War: Warhammer III freeze at 80% loading?

I was losing my mind when deploying thousands of soldiers; the loading screen would just freeze at 80%, doubling my wait time and killing the vibe. I tried disabling all background scanning software in Windows, but disk throughput barely budged and the freezes persisted. I finally used GamePP NVMe Queue Depth Configuration to raise the read queue depth from 1024 to 2048 and tweaked the write cache flush strategy. CrystalDiskMark confirmed 4K random reads jumped to 68-75 MB/s, and AIDA64 showed stable temps at 48-55℃.
