TL;DR Summary
Are particles the kinetic energy of its field?
Trying to better understand quantum field theory, I've read that particles are created when it becomes an exitation of its quantum field. Would it then be right to think of a particle as the manifested kinetic energy of its field?

No. "Particles" are particular states of quantum fields, but particle states will, in general, have other types of energy in addition to kinetic energy, and quantum field states which are not particles will, in general, have kinetic energy, so "kinetic energy" is not a useful way of distinguishing particle states from other states.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
