getting “URL key for specified store already exists.” error when trying to apply data patch to update a cms page

I am trying to update a cms page through a data patch but, the patch is not applying. I get this error below

Unable to apply data patch VendorModuleSetupPatchDataCreateRegistryPage for module vendor_module. Original exception message: URL key for specified store already exists.

I have the below code for my data patch

class CreateRegistryPage implements DataPatchInterface

    /**
