That was the issue. I was editing the "FieldOfView" value in the options.json, and not in the UserSettings.json. Setting the value back to 80.0 in the options.json and 104.95 in UserSettings.json fixed my issue.
Thank you for the quick response.
Seems like patch 2.1 might have borked editing the options.json file. I tried changing the max FOV to 130 and then 110, and both times it threw an error. Changing them back allows me to play.
Anybody else having this issue?
Looks like the update that came out yesterday might have changed a lot of these settings. None of the settings existed in the files and even after adding them it didn't seem to affect anything.
