Thats strange. I have’nt got a official build installed at the moment to check against but if you dont need it you can always delete the plugin folder from your engine install. It should be located in engine/plugins/runtime/. Or you can back up your .uproject file and open it up with notepad to disable the plugin by setting ‘enabled’ under the plugin name to false.
Maybe @getnamo or someone elese can have a look at whats going on.
