I think you are trying to run the default environment in AirSim using Unreal Engine 4.27 and AirSim 1.8.0. However, you are encountering an error stating that the AirSim plugin cannot be found. This error suggests that the AirSim plugin is not installed or is not in the correct location. You may want to check if the AirSim plugin is installed and if it is in the correct location. If it is not installed, you can try installing it and then running the environment again.

Thank you genius... Everyone can read, don't state the obvious. The real question is why is the this problem occurs after following the steps of the documentation and how to check/install the airsim plugin properly..

Note, for those still trying to debug this - unless I missed it - I had the same error. Fixed by manually symlinking the built version of the plugin into the shared UE engine plugins folder.
