Looking at this from a carpenter's point of view ..
the wood under the bridge has torn. It doesn't look like the glue gave out but rather the glue held strong enough to sheer the wood.
The bent metal retaining bar is another clue.

To me it looks like the guitar went thru some type of event. Doesn't look like a defect to me, more like the guitar got damaged.
Maybe it happened three months ago and it weakened over time until today, but no, I've never seen a guitar bridge come off like that.
Show us the bottom of the bridge. Is the missing body wood still stuck to it?


I do not work here, but the benefits are still awesome
