    I'm developing with a simulator by pairing with a Mac from VS on Windows.
    After updating VS, I got the same situation,
    It was solved by updating Xcode, Xamarin.iOS, etc. to the latest version on the Mac side.
    The update process when pairing from Windows to Mac did not solve the problem.
    I had to perform the update process on my Mac.
