You are using the "CONTOUR_LINES" image pipeline plugin. It requires IRRADIANCE AOV to work but BiDir doesn't support that type of AOV so it is just zero (if you save the image you will see that the IRRADIANCE.exr is all black).
"CONTOUR_LINES" displays a grid over regions with zero values and this explain the strange tiles you are seeing.

You can disable the plugin if it isn't needed or switch to normal path tracing if it was needed and you want real irradiance values.
