HI @JanetStandeford ,
If you are using 5.6 version then it’s a known bug and should be fixed in the next update
You can try doing this:
-
First of all, go to the Epic Games Launcher and click on “Verify”
-
Then go to the folder where you have a working version of Unreal Engine installed (e.g., UE 5.4 or UE 5.5, depending on the one you have), Inside that folder, navigate to:
Engine > Binaries > DotNET
(There you should find files related to SwarmAgent.) -
Copy the entire DotNET folder and go to the installation folder of Unreal Engine 5.6 (or the version where you’re experiencing issues)
4.Inside its structure, navigate to:
UE_5.6>Engine > Binaries
-
Right-click inside the Binaries folder and select Paste , when the message “Replace the files in the destination” pops up, ignore it and click “Skip these files” (Do not replace the existing files).
-
Open your project in Unreal Engine .
At the top menu, click on Build and then select “Build All Levels” .
7.You should now see the expected message
You can also read that post , they were talking about that.
Hope it helps!
