Why does Monster Hunter Wilds freeze at 70% loading on Intel i5 13490F?

During mission loading, the game would freeze for 1.2s at 70% progress, which is terrible for a hunting game. I tried installing the game on different partitions, but loading time actually increased by 1s—a pointless attempt. I used the GamePP Resource Scheduler to set the main process to Highest priority and restricted background resource theft. RTSS showed frame times converged to 12-18ms from 16-50ms, and AIDA64 showed CPU temperatures at 65-72℃.
