Fs-ct6b controller not working properly

Hi my name is Nikhil and I brought a Flysky CT6B controller like for 9 months and it worked all fine when today I was trying to make a servo spin it was not working I tried all channels and it was no use I even connected it to my laptop so see if the output of the controller is fine and it was fine and it even binded with the receiver but it still have no response please help me troubleshoot this so that I can complete making my drone

What does this have to do with Arduino?
