VS2022 Node.js Debugging Error: Unknown thread id '0' When Closing Console

I'm developing a Node.js web application and recently started encountering an error in Visual Studio 2022 during debugging.
The issue occurs when I close the console window while the debugger is paused at a breakpoint or after an error. After a few seconds, I get error messages like these:
Clicking OK results in another error after a short delay:
I haven't used Visual Studio for months, and I upgraded from Windows 10 to 11 in the meantime, so I am not sure when the problem started. Here’s what I’ve tried so far:
- Reinstalling Visual Studio
- Deleting the .vs folder
- Testing with a blank project
- Updating Node.js to version 23.6.1
Notably, other project types like C# console apps and Blazor web apps work as expected, which points to a Node.js-specific issue. Google searches for these errors have not yielded any useful results.
UPDATE
I posted this issue on the Visual Studio forum and was advised to use the preview edition, which appears to fix the error. For now, using the preview edition is a viable workaround; future updates should resolve this in the stable release.

Based on your description and updates, it appears you're hitting a known issue in Visual Studio 2022 when debugging Node.js projects. This issue manifests if you close the console window while the debugger is paused (either at a breakpoint or due to an error), resulting in the subsequent error dialogs and delay when you resume debugging.
What We Know
- The error only occurs when debugging Node.js apps.
- Other project types (e.g., C# console apps, Blazor web apps) are not affected.
- The problem persists even after reinstalling Visual Studio, deleting the .vs folder, and updating Node.js.
- Visual Studio's own forums have indicated that the issue is resolved in a preview edition of Visual Studio.
Workarounds & Recommendations
-
Use the Preview Edition of Visual Studio
Since the forum suggestion indicates that the preview edition fixes the issue, you can use that edition for your Node.js development until the fix is backported to the stable release. -
Avoid Closing the Console Window
While not ideal, as a temporary measure ensure that you do not close the console window if the debugger is paused. Continuing debugging before closing the window can help avoid the error. -
Keep an Eye on Future Updates
Monitor release notes for Visual Studio updates. The fix should be incorporated into a future stable release, eliminating the need to rely on the preview edition.
Final Thoughts
If you depend heavily on debugging for Node.js in Visual Studio, the preview build seems to be the most straightforward solution for now. Also, consider reporting or tracking the issue on the Visual Studio Developer Community site to stay updated on progress.

I followed you steps and can reproduce this issue in VS2022(17.12.4). I also noticed an error message "The thread 'app.js [11036]' (0) has exited with code 0 (0x0)." in output window. Looks like it's a product issue.
I would suggest you to report this issue at Visual Studio Forum. That will allow you to directly interact with the appropriate product group, and make it more convenient for the product group to collect and investigate your issue.

Check Node.js Debugging Settings
Ensure you have the correct debugging configuration in your project settings:
Open your project in Visual Studio.
Go to Project Properties > Debug.
Verify that the Node.js executable path is correctly set. It should point to the Node.js runtime installed on your system.
Ensure that the "Enable Node.js debugging" option is selected.
