"Feature 'XXX' is currently unavailable due to an internal error."

Question

Visual Studio 2022 recently started (for absolutely no reason) displaying the following message(s) at the top of the Visual Studio 2022 window:

Feature 'Diagnostic analyzer runner' is currently unavailable due to an internal error.

Similar messages are displayed for many other features (the list is endless!). This started happening for no reason, I did not change (or even open) the settings or preferences, I did not create (or even edit) any files, I did not install any updates, I barely used my computer. Here is a screenshot of the messages:

If I close all the files, it sometimes lets me click the X on the right to get rid of the messages, but then they come back when I reopen the files. What is the problem? I have not tried to repair Visual Studio 2022 (that is, in my opinion, a last resort, since it doesn't always fix the problem). I currently have:

Microsoft Visual Studio Community 2022 (64-bit)
Version 17.0.4

Answer 1

I have the same errors on every tab change in editor (VS 2022 17.4.1)

Same Issues. Started after upgrading to Version 17.4.1.

Answer 3

I closed my project and restarted again. The issue was gone , at least by the time I am writing this feedback.

Answer 4

Have the same issue after upgrading to version 17.4.1

Same here :-(
