[BUG] Valid markdown links in Claude Caude VsCode extension do not open files

What's Wrong?

The links Claude code gives me to files in my workspace do not open. They're clickable, but nothing happens. I have tried:

• Asking Claude to use absolute paths, did not work
• Asking Claude to use relative paths (the default), did not work
• Asking Claude to show me the markdown for the links: nothing obviously wrong with it -- I can use the same markdown in a file at the root of the workspace, preview it in a VsCode editor, the link works

I've also tried mucking with the paths, in case for some reason the Claude window considers itself inside a different directory than the workspace root, like adding ..\ or conversely removing some of the leading directories,

I'm on Windows.

Interestingly: the following works:

• Clicking a file link from Claude's "thoughts". E.g. "Read [file...]", or "Edit [file...]", those correctly open the file when clicked
• Using a WSL projects, when that's the case, all the links work fine. I can't use WSL for this project though.

Even Claude gave up: "I'm out of ideas - we've tried backslashes, forward slashes, absolute/relative paths, with/without line numbers, and different formats. Since markdown links aren't working but plain text paths are clear enough, should I update CLAUDE.md to just say "provide plain text file path instead of links"?"

What Should Happen?

The links provided by Claude code should be clickable.
