DM-33786: Remove try block for stacking

[yalsayyad]

because log.fatal does not exit.
There is still a log.debug that prints each bbox in the loop
if more info on which subregion it is working on is needed.

Ah, so the thought was that the fatal log would exit, but instead it just continued with a bad section? And removing this will let it die in peace.
