Interference?

I probably would, yes. The rules stating a runner interferes with a fielder throwing the ball (NFHS 8-6-10, ASA 8-7-J-2) have no exceptions in effect when the fielder is at the runner's base and the runner goes in standing up. The only exception I know of is when a runner executes a legal slide.

In fact, one could easily argue that a runner who goes in standing up at second and colliding with the fielder is actually showing intent to interfere, and intent is not a criterion that must be met when it comes to interference with a fielder throwing the ball.
