That single branch that’s wilted is done. Chop it off and continue with what you have.
I had to cut the effected branch off ,the rest of the plant is doing great,will never get her (as I know now what sex it is),back to what she was going to be but onward anyway.nice tape job, i broke the main stem of a tomato plant clean off, just a couple inches above the soil, tape it back together and it was fine. how did your turn out?
