I hit same issue on Ubuntu 24.04

Also an issue in WSL Ubuntu 22.04.5 LTS. Running the chmod 0777 . -R on all the project files did help, however, I doubt that it can be called a solution 😆

It wasn't a permission issue in my case, but it was gone after restarting the editor.

I also encountered the same issue on Windows 11:

2025-12-01T10:46:06.0093393+08:00 ERROR notification handler failed handler=textDocument/didSave error=file not found: d:\DevProj\xxx\Cargo.toml

This issue occurs when saving Cargo.toml in the project root directory, but when updating Cargo.toml in a member directory, Cargo checks out normally. Has anyone else encountered a similar issue on Windows?

I looked at issue #19528, but that's not the cause of the problem I'm facing.

Yeah I just noticed the same thing. Windows 11. Vscode with rust-analyzer extension.

My root Cargo.toml looks like this:

[workspace]
members = ["www", "xxx", "yyy", "zzz"]
resolver = "3"

[workspace.package]
version = "0.1.0"
edition = "2024"

[workspace.dependencies]
thiserror = "2"
rand = "0.9"

Haven't noticed anything else working incorrectly.

I encountered the same issue with the Cargo.toml in a subdir from the project root. Directly opening that subdir in vscode/cursor worked fine.

project/
├── my_crate/
│   ├── Cargo.toml
│   └── ...

I found a workaround: using File -> Add Folder to Workspace to add the subdir (e.g. my_crate) to the workspace resolves the issue for me. You end up with the folder in there twice but oh well.
