Hi Siddharth,
Sorry for the issues with the plugins. I think you might have a corrupted plugin folder (or a mix of older and newer versions of the plugin). Assuming that you are using MATLAB R2021b, I would suggest the following:
  • Uninstall and reinstall the UAV Toolbox Interface for Unreal Engine Projects
  • Delete the following folder in the Unreal Editor installation (21b uses Unreal Editor 4.25): c:\Program Files\Epic Games\UE_4.25\Engine\Plugins\Marketplace\MathWorks\
  • Follow the steps here to copy the project and Unreal plugins
  • Open the UE project through MATLAB, as described on this page (using sim3d.Editor)
If this still doesn't work, please reach out to MathWorks tech support to analyze your situation further.
