It sounds like list your GST construct is not binding to the column (or very well) when the peptidase is attached. GST needs to form a dimer to binding to the column - I suspect that your construct interferes with dimer formation - when the peptidase is present, but when not there due to stall

I cannot say what you have - running a gel, MS, etc of a washed crystal could confirm what you have. What you did not indicate is if your lack of diffraction was of frozen or unfrozen crystals. I have seen too many cases where it is the cryo condition killing diffraction. So if you have not tried
