System.Runtime.InteropServices.COMException in visual studio log file

I use visual studio 2019. When I open my solution, sometime I can see this alert:

If I click by Open log btn, I can see a log with the following exception:

System.AggregateException: One or more errors occurred. ---> System.Runtime.InteropServices.COMException: Element not found. (Exception from HRESULT: 0x80070490)

===================

So, actually, it was not a problem for me, before this time. Now I need to install this plugin. And it seems to me, this error prevent for correct installation.

I go to Extensions -> Marketplace -> type "typewriter" - plugin name. Then I press Download. After this I try to restart Visual Studio. Finally, I see the following message:

"Элемент не найден" - means: element not found.

I press on the View install log and again, I see exception about COM:

   в VSIXInstaller.App.Initialize()
   в System.Threading.Tasks.Task`1.InnerInvoke()
   в System.Threading.Tasks.Task.Execute()

So what is wrong?

Full visual studio reinstall solved my problem! And don't remove installation cache according to this
