Visual Studio Code – Buildig time: "The requested operation cannot be performed on a file with a user-mapped section open"

I know this question is on this site. But all answers are associated with some program statement.
In my case no.
I updated Visual Studio to Microsoft Visual Studio Community 2022 (64-bit) version 17.8.3, and after that I can’t build a very simple (i.e. template) console project. The ClassLibrary project is building normally.

My code in Program.cs:

// See https://aka.ms/new-console-template for more information

Console.WriteLine("Hello, World!");

That’s all.

My error:

Any ideas about?

I tried the Debug/Release configuration, searched for answers on this forum – to no avail.
But I found a very important fact:
The “Startup project” item in the solution properties is not checked.
After checking this point and rebuilding the project, this error still occurred.
AND!
This item is again unchecked.
