Why does Cyberpunk 2077 freeze at 80% loading on Zhitai TiPro9000?

Whenever I entered high-density crowds in Night City, the loading bar froze at 80% for several seconds, creating a huge sense of anxiety. I tried cleaning system redundant files to free up 200GB, but the stuttering persisted, which was very discouraging. I used the GamePP Resource Scheduler to set the main game and decompression processes to Realtime priority and limited background I/O. GamePP monitoring showed disk activity dropped from 98% to 65-80%, while HWiNFO64 showed 45-55℃ and CrystalDiskMark measured throughput at 5000-6500 MB/s.
