Ultrawide Resolution not working on PC

Not sure if this is an issue for anyone else as it’s rather specific. I’ve been completely fine gaming in Ultrawide resolutions just logged on tonight and have black bars on either side of my screen. Is this an issue for anyone else?

Not that I know of, it’s an issue not apparently not a well known issue. I hope the devs notice it because it’s very annoying not using that extra space on the side.
