I haven't had this problem before.
I have created a blank solution in Visual Studio 2019 and then, I created an ASP.NET Web Application (.NET Framework).
I did nothing else, just run the application.
After rebuilt, this error was shown:
Unable To Launch IIS Web server. Failed to register URL "https://localhost:44374/" for site "MyProject " application "/". Error description: Cannot create a file when that file already exists (0x800700b7)
I have searched for a possible solution but I did not find someone with the same problem.
How can I solve it?
EDIT:
When I launch IIS Express by command line, the same error exists, but only for https URL of the site:
