IIS (There was an error while performing this operation)

This error occurred for me when trying to double-click on the Logging module for any site with a bad Web.config.

"Bad" includes Web.configs that just have a module IIS doesn't understand - in my case, IIS 10 couldn't understand the <rewrite> tag, and exploded with this extremely confusing error.

You can verify this by just commenting out the contents of your Web.config. The error goes away - then just gradually reduce how much is being commented out until you find the culprit, and track down that solution.

Add <aspNetCore> back and also install ASP.NET Core module on this machine,

I also wrote a tool to better automate such detection,
