The Flight Simulator 2020 version of the MD-11 has a much more detailed freighter cabin than the current Flight Simulator 2024 edition. This is because we've made the low-poly version of the cabin the only version for now.
This is temporary and due to a bug in the simulator itself. Asobo is aware of the issue and you can see our report and their response on the Flight Simulator dev support forums here: https://devsupport.flightsimulator.com/t/looking-at-object-causes-sim-crash-with-s-ok
Once a solution is developed or provided to us, we will update the aircraft to re-enable the high-detail cabin.
