HELP, 2x2 MISALIGNED AND CANNOT PROPERLY TURN

[Cuber Score]

So, I got a new 2x2 today, and it is a very good cube. It turns smoothly, all corners can twist (unlike my last cube), and it has better corner cutting. However, while using it I suddenly had trouble with it. I could not turn the top layer (and still cannot) properly, and all except for two pieces are not symmetrical as they should be, but rather appear twisted as if they were 3x3 corners and their bases were twisted. I determined the cause of the issue to be that the pieces of the layer somehow misaligned with the center, because the center aligns perfectly but the corners don't. How can I fix this, if at all?

Attatched below is an image of the 2x2:

Maybe a internal pop, maybe you bent the corner stock somehow.

I would try to disassemble it.

Stalk not stock. Just a FYI.
