Why does Gray Zone freeze at 85% loading on Colorful B760M?

Whenever I enter a warzone map, the loading screen freezes for 2-3 seconds at 85%, which really kills the momentum. I first tried updating to the latest BIOS version, but the loading time barely changed, making me very cautious about the process. I used the GamePP BIOS Load-Line Voltage Adjustment Wizard to switch LLV to L3 mode and fine-tuned the Vcore offset to +0.01V. Cinebench R23 showed multi-core frequency stable at 4.8GHz, and HWiNFO confirmed VRM temperature stable at 52-60℃, with voltage at 1.18-1.32V per GamePP Hardware Sensor.
