You can restore a hot wallet by just reentering the BIP 39 mnemonic and if you had labels you can simply import the labels via the Specter json file. This process is not explicit anywhere, there should be more guidance in the UI for the user to know about this process.
When you reimport the hot wallet in Specter (with the same name as before) and you haven't manually deleted the wallet file on your node, you get this error right now:
