Since the last couple of updates to Visual Studio 2019 I find that my solution "hangs" very often when I rebuild it.
After some investigation it seems to me that this issue arises when the "Error List" pane is shown

When I close the Error List pane the build doesn't "hang" and it runs to completion.
I have tried various other things. For example building only the main application or building the entire solution, debug or release configurations, x86, x64 or AnyCPU platforms, none of it makes a difference.
Any idea what may be going on here?
