[v0.3.2571] Error hints disappear after saving a file

[ZGBX]

Problem Description

When using the rust-analyzer extension (version v0.3.2571), the code error hints briefly appear and then quickly disappear after saving a file. The error hints only persist when VS Code is first opened.

Extension Version

rust-analyzer v0.3.2571

VS Code Version

1.103.0

Operating System

macOS 15.4

Reproduction Steps

1. Open a Rust project in VS Code.
2. Make a change to a Rust file that introduces a syntax error.
3. Save the file.
4. Observe that the error hints briefly appear and then disappear.

Expected Behavior

The error hints should persist until the errors are fixed.

Additional Information

• This issue only occurs after the first save. The error hints persist when VS Code is first opened.
• I have tried restarting VS Code and my computer, but the issue persists.

Oops, I might have messed up something with #20419

Sorry, I'll fix this in few hours once I'm back home. I think we need another stable release for this 😢

Could you tell me when it will be released? thank you

[ShoyuVanilla]

Maybe within 8 hours or so? Please use the previous stable release before then. Sorry

A hotfix has been released with the version 0.4.2572 in pre-release channel but not yet in stable release channel

This should now be fixed in the stable release (0.3.2575).

I still see a similar issue:

Cargo check failed to start: Cargo watcher failed, the command produced no valid metadata (exit code: ExitStatus(unix_wait_status(25856))): error: no library targets found in package service-rust

Extension Info: Version 0.3.2575, Server Version 0.3.2575-standalone

As a workaround, a "Reload Workspace" command (on the rust-analyzer "tab" at the bottom pane), temporarily fixes the issue.
