Modular Build does not start, can't load module

I want to build my game with modular link type.
So i added “LinkType = TargetLinkType.Modular;” to the Target.cs.
It builds fine. All modules are compiled into DLL files.

But when i want to start the build it says:
“Plugin ‘GeometryCollectionPlugin’ failed to load because module ‘GeometryCollectionNodes’ could not be loaded. There may be an operating system error or the module may not be properly set up.”

The module for that plugin is present. It is there as a DLL file.

I am using UE 5.4.1 source version.

Any idea what could be the problem?
