UE4: This project requires the 'AirSim' plugin, which could not be found.

I built Airsim on Windows 10 using UE4.27, didn't see any errors in the output, yet when I add the Plugins/AirSim folder to the UE4 project and try to open the .uproject, it gives me this error. I tried cleaning and rebuilding many times

I also ran into this issue. For me it was due to cloning and running build on the C: drive.
I used an external HDD and cloned/build.cmd the repo there.
Dragging and dropping the Plugins/AirSim folder into my project now detects the plugin.

Following the steps outlined here: Build AirSim on Windows
it also mentions to clone onto a different drive than the C drive.

Setup:

• Windows 11
• vs2022
• UE 4.27.2
