HResult=0x80131501 on my new Win11 32bit machine (no replies)

This the closest match I could find to post my query, although connector is not explicit in the code. Note: ctor in code below refers to the constructor.
When I login to MySQL 8.3 Command Line Client, I get no error. The connection works fine in HeidiSQL also. When I run my code programatically I get the error.
Message=A call to SSPI failed, see inner exception.
Source=MySql.Data
Inner Exception 1:
Win32Exception: The message received was unexpected or badly formatted
Here is the code:
public void MakeConnection()
{
string connectionstring = "Server=localhost; UID=root; Pwd=<mypassword>; Database=MyDatabase;";
con = new MySqlConnection(connectionstring);
if (con == null) return;
con.Open();
cmd = con.CreateCommand();
}
It throws the error at con.Open(); Interestingly, when I run the exact same code on my Win 8.1 32bit machine, I get no error. Obviously a different instance of MySQL, since both are localhost.
The password is NOT misspelled. Re-typed numerous times in program and command line to be sure.
Here is the stack trace for the error in case that helps:

I am in the process of migrating lots of stuff from my win 8.1 machine to my win 11 machine.
What can I do to make this work? Thank you.
