Comment:

It seems you are not isolating the photon from quarks. That's why photon-quark singularities get into your matrix elements which make them very inefficient, and as you have noted also in your other email make the integration times diverge. Try with the following additional line in the selector section:

DeltaR 22 93 0.7 10.

(adjust the 0.7 to whatever kind of photon isolation is loose enough for your analysis)

Does that solve it?
