22 is simple one - air intake temp sensor - very easy to leave this unplugged if you had the airbox off for maintenance.
19 is the sidestand switch - make sure that is plugged in & operating properly. Sidestand needs to be up (Switch made) if bike is not in neutral.

19 is associated with the sidestand interlock
The bike must be in neutral or have the sidestand up. These interlock the starting cut-off relay.
Does your neutral light work? If it does not, that needs to be resolved, but bike should still start if the sidestand switch is made (stand is up).
If bike still does not start, then you may have problem with the diode assembly or the starting circuit cut-off relay.
