I want to run three instances of the same browser, but so that their authorizations do not meet each other. I want to use incognito mode. Now I use different directories to store cookies, but sometimes the application does not want to delete this directory after I close my application.

Try calling TWVBrowserBase.ClearDataForOrigin('*') instead of deleting files.
