“Failed to initialize Swarm. Check to make sure you have the right version of Swarm installed.”

Solution for Unreal Engine 5.6.0 Error:

To resolve this issue, navigate to the following directory: \Unreal\UE_5.6\Engine\Binaries\DotNET

Once there, add the files from the DotNET folder of version 5.5. This will temporarily fix the error until a UE update is released.

If you don’t have version 5.5, I’ve shared the folder with you simply copy and paste its contents. Important: Only copy the contents of the folder, as the original DotNET folder contains other essential files.

Recommendation: Back up the original DotNET folder before making any changes.
