There are a few causes of resin prints failing, but the most common is over-exposure to light. This can be caused by using a print scanner that doesn't have a sufficient light shielding or by exposing the prints to direct sunlight or fluorescent lighting. Another common cause of resin prints failing is improper curing. This means that the resin didn't properly harden and can often be corrected by heating the print until it softens and then re-curing it.
