Something loose/broken inside German Bass Bow

A couple days ago, I rested my German bow down on a table. There was nothing about where I put it that was particularly dangerous. When I came back, it was in the same exact spot. However, there was a problem with it. There was something actually inside my bow that had come loose or been broken. You can think of it like a hula hoop with beads inside of it to make it rattle when you spin it. It still functions properly. I can still tighten and loosen the bow as I could before. It just sounds like a maraca now.

I've tried opening up the bow by taking off the screw at the frog, but it seems whatever is stuck inside it is too big to come out through the hole.

I'd like to know what is the actual problem with the bow. Although I'd like to be able to fix it myself, I'm fairly certain at this point that I'm going to need to take it to a shop. One can hope, I suppose.

As I've mentioned, the bow is German. It is made up of carbon fiber. I have owned it for about half a year at this point. I have treated it with care the whole time I've had it, as I bought it myself.

Any help is sincerely appreciated. Thank you.
