I have also NeuralNetworkInference and NNI folder in Plugins\Experimental but I do not have any uplugin file in NeuralNetworkInference only ThirdParty Source folder for ONNX Runtime.
So not sure why you would have that…maybe try run the validation and see if it update something. Or if you don’t use it could try to move one of them or both and see if it work better.
I do not have the latest update for UE5 so it might be something new if you have it updated.
