AO is working for me. I don’t have “RealTime Global Illumination” switched on. My “Bake Backend” is set to Enlighten. Maybe try that and see what happens?

You’re settings are very far from the defaults (Indirect contribution at 9.96, max distance at 300 etc). Maybe try resetting back to defaults and working from there? Maybe you can find a specific thing that is breaking it then. YOu ca reset using the cog in the top right, right click → reset I think.
