DevTools failed to link network resource to filesystem.

Platform: Win 10 
Chrome version: Version 64.0.3282.119 (Offizieller Build) (64-Bit)

There is nothing special on the project - it's just a private enterprise project, so no public link to the project available.

I used the Chrome's workspaces and mapping-http-resource-to-workspace-file feature now for years - but this new 'magic' i-can-reveal-the-mapping-to-the-workspace feature seems to be a total crap - It simply does not work. Nothing happens, nothing mapped, we can't develop any more with Chrome like we did for years.

As we can't even map manually, the workspace feature is now totally useless.
