Remove the starter motor and inspect the teeth on the ring gear and the starter drive gear. If they are okay, either the starter drive's over-running clutch is bad or the flex plate is broken around the center where it bolts to the crankshaft.

You can also try turning the engine a little by hand, then try starting it. If that works, suspect worn ring gear teeth.

The generator has nothing to do with starting the engine unless the battery is discharged.
