Notes:
1. The full error: “Failed to present D3D11 swapchain due to device reset/removed.This error can happen if you draw or dispatch very expensive workloads to the GPU, which can cause Windows to detect a GPU Timeout and reset the device. (see https://docs.microsoft.com/en-us/windows-hardware/drivers/display/timeout-detection-and-recovery).If you believe this error is due to built-in Unity functionality, please submit a bug.This is an unrecoverable error and the editor will shut down.“
2. Could not find the exact ‘Fixed in’ version due to reproduction being inconsistent
