How to fix Dota 2 freezing at 90% during the loading screen?

Every match start was a torture; the loading screen would freeze at 90% for seconds. I first tried disk defragmentation via Disk Management, but for an NVMe drive, this was a waste of time and actually slowed response speeds. I then used GamePP NVMe Queue Depth Configuration to increase depth from 32 to 128. CrystalDiskMark showed random reads improved to 58-65MB/s, HWMonitor showed 35-48℃, and loading times dropped from 12s to 6s.
