Unable to deploy and debug application Extension backend error - there are no rsp providers registered.

I get this error suddenly when I create the new server. It was originally okay. What should I do?

This is a strange issue I've never seen before. Are you sure you have both extensions (rsp-ui and vscode-server-connector) installed?

The vscode-rsp-ui extension manages the ui, and other extensions can plug in and provide contributions to it. This type of error would only really be present if you somehow removed or uninstalled the server-connector extension while keeping the rsp-ui extension.
