Squawking Sound from Jack

Picked up a second Stingray5 last year, and have noticed an intermittent issue with the cable jack. Any pressure on the cable side-to-side (as, for example, when I bump the cable with my hip or leg while moving around) causes a squelching/squawking sound. Seems like cable tip has just enough play or room to move that it’s somehow causing some kind of short. Tried various cables, unplugging, replugging, and it’s clearly an issue with the jack.

Obviously, I don’t really know what I’m talking about, which is why I’m posting here. Anyone run into something like this before? Thoughts on how to resolve it? My current plan is to take it into a local luthier to get it looked at and possibly replace the jack. Kind of frustrating though, since it’s a $2200 instrument that has spent pretty much it’s entire existence packed away in its case. Thanks in advance for any advice.
