Why does Deathloop freeze at 80% on Zhitai Ti600 500GB SSD?

I was losing my mind when the loading screen would just freeze for three seconds at 80% during fast-paced loop jumps. I tried disabling all background update services in Windows, but loading times only dropped by 0.5s, which was basically useless. I finally used GamePP NVMe Queue Depth Configuration to raise the queue depth from 32 to 128 and enabled forced write cache flush. Now, random 4K reads hit 65-78 MB/s per CrystalDiskMark, throughput is 320-450 MB/s via CrystalDiskMark, and temps stay at 45-52℃ per AIDA64.
