Stereo Output for Logic is greyed out. I can only choose Surround Output

I have tried everything and attached screenshots. When I try creating a track, it will only produce sound if the output is set to surround because stereo out or Output 1-2 just doesn't appear. I've gone into preferences 10s of 100s of times in Audio and Midi; in Audio > I/O Assignments, but every time I try to confirm an output, Output and Stereo is always greyed out.

I have checked my audio outputs and inputs. I can hear sound when inserting audio files externally. And any tracks I create can ONLY be heard if they are set to Surround Output since there is none other available.

I'm on a Brand New iMac 24-inch, OS Sonoma 14.4.1
