Old or corrupted PPU and SPU caches can lead to mismatches between what the emulator expects and what it receives from the stored data.
The error message is a critical stop-code indicating that the emulator has encountered an internal state it cannot reconcile. Unlike standard performance issues, this error typically stems from hardware-software desyncs, corrupted cache, or incompatible settings.

If the error occurs during shader compilation, try disabling the "On-Disk Shader Cache" to force the emulator to rebuild shaders from scratch. 2. Manage Game Resolution and Scaling BLES01898 Thread Verification Failed Crash When Upscaled Old or corrupted PPU and SPU caches can

The most effective fixes often involve synchronizing the RSX and CPU threads.
In the Advanced tab, change "FIFO Accuracy" to "Atomic." Combined with enabling Accurate RSX Reservations , this can eliminate up to 90% of desync-related crashes.
