Steps to reproduce

1. Open a TS file in VS Code
2. In your user preferences JSON, add or remove the typescript.native-preview.tsdk option pointing to your local tsgo build to make VS Code switch between the local build and its bundled build
3. In the TS file, run the Restart Language Server command

Issue

An error "command 'typescript.native-preview.codeLens.showLocations' already exists" appears, and then you’re left with two instances of the client running!
