FormatException: Input string was not in a correct format. - Changed ASP.net Core Identity PK to int

I've been working on this for the last 3 hours and haven't found a good resource or solution to this problem. I've followed the directions found in Microsoft's documentation to change my ASP.net Privatekey from a string to an int. Since then, I have been presented with the following error:

FormatException: Input string was not in a correct format.

The app will not load past this method in the program.cs class:

    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

I have hit a roadblock and any help with this issue would be appreciated.

I think the problem may be that the login of your previous user may be completed when the ID is a string.

You now change it to int, so now it no longer knows what to do with the string.

I think the simplest solution is that you should delete the cookie, log out and log in again (use int instead).
