This error occurs when you have an invalid option, e.g. language selection. When you force updated you removed any mods, etc. Did you have a language pack or something similar? In any case you can either edit .minecraft/options.txt or rename it (which will cause it to be regenerated from scratch with defaults)

Thank you! I was using my own private language pack
