ReplicationSystemTestPlugin Built With A Different Engine Version

When I try to open a project with ReplicationSystemTestPlugin enabled, it gives:

The following modules are missing or built with a different engine version:

ReplicationSystemTestPlugin

Engine modules cannot be compiled at runtime. Please build through your IDE.

I know that this happens with stuff like the DLSS plugin, but it is an engine plugin. Shouldn’t it be already built with the correct version?
