Steps to Reproduce:

1. Re-open a folder in a dev container based on the above devcontainer.json and Dockerfile
2. Try to open a file from a mounted directory under /workspaces, either the custom bind mount or the auto mount point for the directory/repo being re-opened in the container
3. The following pops up: "Error: EIO: i/o error, stat '/workspaces/repos/test.txt'"

Does this issue occur when you try this locally?: N/A Does this issue occur when you try this locally and all extensions are disabled?: N/A

I have tried to reproduce on another machine with the same versions as listed above, and I can`t seem to reproduce there. Hence, I am thinking it might be something related to the other machine - which has worked just fine with dev-containers up until now.

After posting the issue I tried to simply reboot the machine. After doing so, the issue was gone and I could access mounted files and folders within all of the 3 dev-containers I had the issue within. Since it is not reproducible, we can close the issue.

Regardless, it would be interesting to know what could cause this problem. Any thoughts?

I can only guess at the moment: Docker Desktop has some kind of a filesystem adapter to allow mounting Windows folders in the Linux containers. Maybe that subsystem got in a bad state and rebooting got it back up. Next time try restarting only Docker Desktop to see if that fixes it before rebooting to narrow down the problem.

Closing for now, thanks.

Reopening in favor of https://github.com/microsoft/vscode-remote-release/issues/9585.

@arghhjayy mentioned seeing this on Windows 11 with Docker Desktop 4.27.2 (137060).

Could you open an issue for Docker Desktop for Windows to track this? Thanks.
