Why does Gears 5 freeze at 90% loading on multiplayer maps?

It was incredibly stressful every time I entered a multiplayer map; the progress bar would freeze at 90% and crash to desktop. I tried updating all my hardware drivers, but loading times actually increased by 5 seconds, leaving me feeling stuck. I then used the GamePP Resource Scheduler to set the game process to High priority and restricted background services. This worked perfectly; loading time dropped to 28s per GamePP timer, and voltage fluctuations were tightly contained within 0.05V per HWInfo64, with temps at 62-68℃ per AIDA64.
