It is quite possible that your clutch is not disengaging the transmission from the motor. Also, your synchros could be bad, which would not allow it to go into gear.
It would be hard to get into gear and would make grinding noises when shifting.
The touch sensor controls on JBL Synchros 400BT cannot be disabled.
Synchros in a manual transmission are used to slow down the gear before it is engaged so it doesnt grind

Worn synchros
Control systems are synchros which are used in error detection. They provide a voltage to be converted to torque through an amplifying method.

Synchros is a mechanic in Stardust Accelerator the player is not able to use till they have almost finished the game. It specifically starts to be usable to the player once they unlock the Duelist Genesis pack.
i really do not think that elemental heros go well with synchros, unless it is an absolute zero deck. he is coming out in January.
