i update my project from 5.03 to 5.1, niagara fluids 3d gas cannot be activated.
i notice a piece of information in the release notes of ue5.1. But i didn’t find HairStrands plugin. What could be the problem?

Disabled dependency on the HairStrands plugin for Niagara Fluids. Old assets may now fail to run properly without manually enabling the HairStrands plugin for access to the NiagaraDataInterfacePhysicsAsset class. Newer assets are no longer dependent on this plugin, and in the future the class itself will be migrated to the Niagara plugin.

Set Default RHI to DirectX 12 in Project settings > Platforms > Windows solved this problem.
