MarkLR, Oct 17, 2016 : I can also confirm that changing the language to English fixes the problem. I seriously hope OnePlus realize the f-up and release a quick hotfix. I really don't want to have my PIN disabled or keep my phone in English. By the way, while the phone is spazzing out, if you wait a long time (around 5 minutes) it will allow you to go on but the simcard will not be detected. This way you can try the workaround without having to remove the simcard (worked for me as I didn't have any tool ready to remove the simcard, not even paperclips). I also wanted to add that the obnoxious bug with the power saver removing screen rotation and GPS with nothing you can do about it is still there and anoys the hell out of me. I'm seriously considering going back to stable OOS because of this. Other than that it's too early to tell which bugs are still present other than this one, for me.
