Conflicting Namespaces on Build

I have some optimization tool plugins from Fab installed to my engine. When I try to build the project, I get a pair of errors indicating that two plugins share the same namespace.

VS Errors

The namespace ‘’ already contains a definition for ‘OptimizationTools’
Type ‘OptimizationTools’ already defines a member called ‘OptimizationTools’ with the same parameter types

Build.bat Errrors

Localfilepath\Epic\UE_5.5\Engine\Plugins\Marketplace\Optimizaxxxxxxxxxx25V6\Source\OptimizationTools\OptimizationTools.Build.cs(5,14): error CS0101: The namespace ‘’ already contains a definition for ‘OptimizationTools’

Localfilepath\Software\Epic\UE_5.5\Engine\Plugins\Marketplace\Optimizaxxxxxxxxxx25V6\Source\OptimizationTools\OptimizationTools.Build.cs(7,9): error CS0111: Type ‘OptimizationTools’ already defines a member called ‘OptimizationTools’ with the same parameter types

In my UE_5.5\Engine\Plugins\Marketplace directory, I have two Optimization folders:

Optimizaxxxxxxxxxx25V6

Optimizaxxxxxxxxxx3cV8

Each contains a file named “OptimizationTools.uplugin”

One solution would be to have the .uplugin filename and the plugin namespace also include the marketplace hash.

Is is possible for me to edit the plugin code? Has anyone done this?

One of the optimization tools was not yet in my project’s plugins list, so I was able to delete it from the engine directory. The project has since completed a successful build.
