Mouseover for RustAnalyzer not working in VSCode.

[Nucl3arSn3k]

After fixing my rust analyzer install, mouseover doesn't work for showing me the details of what type a variable is. I've tried disabling and reenabling it, and I've also tried reinstalling the rust analyzer executable as well as the extension. What else can I do to fix this?

I'm also getting this error,which could be related.
[ERROR rust_analyzer::dispatch] unknown request: Request { id: RequestId(I32(14)), method: "rust-analyzer/fetchDependencyList", params: Object {} }

I suspect you have a mismatched extension and server binary. Did you set rust-analyzer.server.path? The extension comes with a bundled server, and you don't need to change it on the major platforms.

If that doesn't fix it, please file an issue in the proper repository and include the required information (version, settings, code sample etc.).

I'm getting a similar error and I don't know why or what is triggering it. I've been getting it for a few days and mostly ignoring it but figured might be worthwhile mentioning it. Only rust code I've been working on recently has been my Shuttle CCH Solutions so I'm not sure if it's related to that code specifically or a new RA. Putting a copy of the log below, happy to provide more info as needed.
