My emax 22l HST has a loud knocking or hammering noise from the starter motor. No engine turn over! Wont Start! Help Please!

I'd start by shifting into neutral - perhaps a space between ranges - to see if the starter will turn the engine over. If not try rotating the engine by hand, perhaps using the front crankshaft bolt with a socket and breaker bar. This will let you know if the engine is seized.

Starter gear may either not be meshing with engine or the solenoid that pops out the shaft is not going out far enough.
If you can turn the engine a little safely and then try, it would rule out engine seized and starter gear not meshing in one go.
Make sure you are in neutral during any of this testing.

You could also pull the starter and examine the teeth on the ring gear and the starter. The knocking could be worn down teeth slipping past each other
