I on the node - red on the interface at first when opening the system suddenly appeared a mistake "the flows stopped due to missing the node types. Movehub - config" because there is no use the node, I just want to try to remove the node, therefore unable to delete the node in the node management, so I restart the node - red check log, there might be in the photo information:

I want to ask how to solve this error? Or how to delete the node?
