Well, If I were you (in fact, I did this long ago...) I'd scrap the vanilla launcher and Install MultiMC. You can transfer all your files and things to MultiMC, but it might fix your issue. My guess is a problem with forge, since it says no class found. If you don't want to mess with MultiMC, I'd try re-installing forge. Then see what happens.
