Well, first issue from your diagram is the servos don’t have any power source.
I realise this may not be your immediate problem, but it does indicate the incomplete nature of the drawing.
If you’re powering the servos from the battery - fine, but show that with connector names on the map, but then the question begs, where is the Arduino getting power from?
Ok, the USB cable... or an adapter? that’s not shown as an active piece of the puzzle either.
Finally, can you test the computer USB with another device that needs power? e,g. phone charging. Just to eliminate that.
With an external Arduino supply connected, what voltage do you see across the GND and 5V pins?
Of course, all this may be moot if your damaged tracks are still damaged.
As your mum used to say...”Take care of your toys!”
Once this has been resolved, go read up on drawing a meaningful block diagram and a schematic (different things). Your block diagram is a good start, but missing about 40% of the detail.
