How do I fix loading delays in Zenless Zone Zero on Sapphire RX 590 GME?

Zenless Zone Zero loads stuck at 90% for 60s. I updated drivers, but the game crashed. I used GamePP Resource Scheduler to set priority to Highest and disabled sync services. Loading time dropped to 15s (GamePP), and frame time stabilized at 16.6ms (MSI Afterburner). This process fix works perfectly.
