A corrupted game dump (ISO, WBFS, etc.) can cause unusual emulation errors.
Right-click on an empty space in the right pane, select , and choose DWORD (32-bit) Value (or QWORD (64-bit) Value if you are running a 64-bit OS). Name the new value TdrDelay .

Disable overlays from Discord, GeForce Experience, AMD Software, and MSI Afterburner, as these compounding overlays increase crash risks. A corrupted game dump (ISO, WBFS, etc
Overlays inject code directly into the graphics API pipeline, which frequently breaks Vulkan applications. Turn off the in your Discord user settings.
The causes and solutions can vary by platform. This table outlines the most common scenarios: | Setting Change | Expected Outcome | Success
In Vulkan, "Device Lost" is a driver-level signal. Unlike older APIs like OpenGL, which might try to "guess" its way through an error, Vulkan is explicit. If the GPU takes too long to process a command (a "TDR" or Timeout Detection and Recovery) or encounters an invalid instruction, the driver kills the process. Common triggers include:
Fortunately, this is a known issue with distinct triggers. This comprehensive guide breaks down exactly why this error happens and provides step-by-step solutions to fix it. Understanding the "VK_ERROR_DEVICE_LOST" Bug
