If you are using 5.6 version then it’s a known bug and should be fixed in 5.6.1 (when it’s released)

> In Unreal Engine 5.6 Preview was an issue with baking static lights because Swarm Manager wasn’t included in Binaries/DotNET. I thought it was a preview issue and expected release version to have swarm manager or remove static ligts support in favor for Lumen RTGI. But I am still able to select None for Global Illumination and still cannot bake lights: Failed to initialize Swarm. Check to make sure you have the right version of Swarm installed. Can anyone from Unreal team clarify what’s going…

or you can fix it yourself for 5.6, read through the topic i linked.
