My guess is, that the clamp connecting handle and bolt work got loose. It is meant to get loose when burglars apply force to the handle to force the bolt work back. Maybe it fell on the handle during transport?
Number 1 recommendation is of course to get a safe tech solving your problem, because doing the wrong things can make the problem worse and create new problems.
If this is not your choice, then I would try to look for another reason to convince the bolts to retract. Depending on the weight I would try to lay it on the hinge side, so that gravity retracts the bolts. Or use something thin to probe the bolts back through the door gap. Or perhaps rotate the handle quickly as there might be still enough friction to retract the bolts.
