Cannot close code review response work items in Visual Studio or DevOps

I'm trying to close a code review response work item in Devops/Visual studio and I get the Field 'Closed Status' cannot be empty error and I am unable to close the work item. The Closed Status is not editable in Visual Studio or DevOps.

I don't want to be editing the "Closed Status" in excel, I need a easier way of handling this. Any ideas?

I can reproduce the same, after investigation, it's a known issue which reported here.

You can use the workaround below to close them:

1. Open the code review requests in a DevOps query.

2. Select the request, on the right side pane, change the state to closed, it will report the error. Ignore that error and continue to step3.

3. click ... on the left pane after the ticket name, click edit:

4. In the popup select "Close Status Code" and pick value 5 and press OK. This will update the Closed Status (which was the cause for the error that we saw in step 2).

5. Now just press Save and the ticket will be closed.
