"If installed on steam go to Steam/steamapps/common/cryptic studios/neverwinter/live/localdata and open gameprefs with a text editor like notepad, change the number after gfxsettings.defaultfov to what ever you want your fov to be. then launch neverwinter and it woll be fixed, but don't touch the fov bar or you will have to do this again."
Found this on a reddit post, thought i'd share for the people who want to be able to play but we're having problems with nausea, ect.
