Re: Origin games won't launch
I started having this issue too a few months back, reason why I ditched Origin for EA Desktop (but I don't like the client at all + it's in beta and it's missing many features)
I removed Origin, reinstalled it, even reinstalled my games (BF5). The worked... but only temporary.
A solution that seems to work every time, so far, is quit Origin and do an End Task on OriginWebHelperService.
