Hobbywing platinum 30a opto not initializing

Hi all.
On my MCW (mini Crosswind) I have two Hobbywing platinum 30a opto ESCs swinging two T-Motor 3110. FC is a Matek h743-wing, throttle channels on default 1,and 2 channels.
The ESCs won’t initialize if battery connected, except if I power the fc first and wait for boot to complete, than connect the ESCs signal wire.
Mentioning that the whole setup was working flawlessly with different ESCs, namely, hobbywing skywalker 60a.
Any help would be greatly helpful.

I have same issue with Kakute H7v2 and same esc.
It seems it is a Ardu related issue because same quadcopter configuration working great with Inav 5.1
The Fc with Ardu does not “see” conected esc ,making 1 beep at start.
I am on last stabile build.
