Why does Ghostwire: Tokyo freeze during fast travel in Tokyo?

I was casting spells in Shibuya when the screen suddenly froze for a fraction of a second, completely killing my combat flow. I tried disabling all unnecessary startup items in the system, but the stuttering frequency barely changed, leaving me totally confused. I then used the GamePP Resource Scheduler to force the game's disk access priority to Highest and adjusted the NVMe queue depth. Frame time converged to 11-14ms per RTSS, disk latency stabilized at 2-5ms per GamePP, and temps stayed 52-58℃ per HWMonitor.
