Seems work to me, can you try different pin?

I tested this with the App button on the Portal board. Works.
And in my real project it works if int0.ValueChangedEdge = GpioPinEdge.FallingEdge;

My test used PF10, same as yours and seems work to me, and other pins work as well. So I don’t think firmware issue.

Is it custom board? Do you have any other boards to test PF10?

Multiple interrupts defined for Px10?

not defined. I have only one custom board.
