What would happen if the Earth's tilt would shift to 45
deg suddenly or in a short period of time? Would we
survive?

The amount of energy involved to cause that would vaporize
the planet and everything on it.

Don't see why would our planet vaporise?


Says more about you and your (lack of) understanding of fairly
basic physics.

Let's say a large asteroid would hit our Moon, knocking it
out of orbit or much farther away, so earth would wobble
more?

An asteroid big enough (or fast enough) to have enough energy
the moon out of its orbit wouldn't knock the moon out of its
orbit, it would shatter it, and turn a great deal of it into
plasma.

And that wouldn't be nearly enough energy to alter the Earth's
tilt that much.

Depends how the Moon is hit and the size of asteroid?

No, not really, To "knock the moon out of its orbit" would require
a certain amount of energy. That amount of energy would shatter the
moon, and turn a good deal of it into plasma. The math isn't that
complicated. (And the debris would probably kill everything living
thing on Earth even if the impact didn't.)
