I'm thinkin a goose hit that blade and weakened it prior to the flight. You'd think a pre flight inspection would have uncovered this.
A bird strike would've caused noticeable damage to the engine prior.
Going by past examples of uncontained engine failures, you will likely find fatigue in the fan blades.so the discussion of the Iranian 737 of the same type being shot down made me want to revisit this thread from nearly 2 years ago. I decided to look into the NTSB findings and see what i got right or wrong on this one so take a look:

The National Transportation Safety Board (NTSB) determines that the probable cause of this accident was a low-cycle fatigue crack in the dovetail of fan blade No. 13, which resulted in the fan blade separating in flight and impacting the engine fan case at a location that was critical to the structural integrity and performance of the fan cowl structure. This impact led to the in-flight separation of fan cowl components, including the inboard fan cowl aft latch keeper, which struck the fuselage near a cabin window and caused the window to depart from the airplane, the cabin to rapidly depressurize, and the passenger fatality.
