I need help with my camera, it's shoot button is stuck! Please suggest anything!

So I went to the beach and my idiot self left my camera on my bag, and while I was swimming the wind picked up and blew a lot of sand on my camera. At first I didn't even think about that problem with leaving my camera exposed. But after a while I came back (it began to rain) and noticed I left the camera and quickly put it my bag, at this point it was VERY sandy, I cleaned the sand off with a brush. But the shoot button is stuck, I cannot press it or unpress it, it's stuck down and not moving, how can I repair this? Did I destroy my camera? I'm really concerned, it still works and takes photos fine, the button doesn't work though. Any suggestions?

My camera: Nikon 3300D

Sorry if this is the wrong place to ask about this, I couldn't find any photography websites where I can ask questions.

...mmmm...It might be time for a Nikon service centre

You could try and disassemble it yourself for a quicker and cheaper fix, but so much could go wrong

I have a Pentax ME that I left out in the rain with the lens off.

And discovered it in the morning, I took the battery out and the film was just soaked.

It still works today (well not much film work recently)

So there is always hope

Hmm, I'll ask nikon sevice, hopefully I get it working, I love photography and now is the best time to do so, having no camera would suck

If you have a scalpel, with a 10A blade, or even a 3d print nozzle cleaning wire, stiff 0.3 mm with a handle, and gently try running it around the button, to see if it releases the grain of sand...
