What causes the 3-second freeze during magic scenes in Avowed?

The TiPro9000 experienced deadlocks during scene loads, with the screen freezing for 3 seconds and GamePP showing I/O queues hitting 100% while speeds dropped below 100MB/s. I tried updating the latest motherboard chipset drivers, but the deadlocks continued to occur randomly, which was infuriating as standard updates failed. I used the GamePP Peripheral Driver Conflict Detection Tool to find a conflict between an antivirus scanner and the NVMe driver, then set the service to manual. RivaTuner showed frame spikes dropped from 120ms to 16-22ms, and HWInfo confirmed drive temperatures were 45-55℃.
