How do I fix input monitoring not working in Logic Pro?

Hi all,

I'm here because I've tried everything I know and nothing has worked. I can't hear a record toggled track with input monitoring toggled as well in the stereo track (or bus, or other output). See here: https://imgur.com/a/2xsAtGb

I get a signal on my track but that signal doesn't go to any track that it's patched to. I can hear everything else on any session and if I do record then I can listen to what I recorded but I can't hear it while recording. I had to cancel a studio session yesterday and send a singer back home (she lives 2 hours away, not great).

What I've done:

• Unchecked "Auto Input Monitoring"
• Reset all logic settings
• Reinstalled Logic
• Update Mac OS to Sonoma 14.7.5
• Updated Logic to 11.1.2
• Tried different audio interfaces
• Tried on old and new sessions
• 
  

What am I missing? I feel like I'm pouring water from a bottle in a glass, I see the water going in the glass but then the glass stays empty. It's driving me insane.

Thank you
