2d character controller jittery movement

Godot Version

4.6.1 stable

My 2d character controller is having jittery movement, when I move away from Monolithic God Script to Component Pattern + Parallel FSMs Using Enums + Data Driven Configuration Architecture.

The player is having jittery movement like it’s being electrocuted. We can see the stutters when the player is moving and jumping in slow motion.

Here’s the project file:
