To stop stress cracks from occurring create an arc using a glass cutter near the crack. This prevents the crack from advancing, and may slow it down by a day or so.

It should be slightly larger than the opening in order to allow for expansion and contraction and to account for any imperfections that may occur on the frame or on the glass.

The spacer is filled with desiccant which is extremely absorbent and absorbs any moisture that is present.
The problem with this is that once the desiccant gets saturated, it will begin to break down, and eventually moisture will begin to leak through the gap between the glass units. This could lead to condensation and water leaking into the gap and is very difficult to eliminate.
Most reputable window companies offer a warranty and will replace the unit and glass of a window in the event that it's damaged by condensation. Make sure to report any issues as soon as possible to the window manufacturer so that the condensation is repaired as quickly as possible to avoid further damage.
