Blugsplash made my account to logout

Scketchup is asking for login after a blugsplash. I am not receiving the verification code. I’ve been waiting for an hour. I need to work!!!

There is a verification code that only comes via email when you first set up the account. After that you should only see authentication code requests if you had set up multi factor authorization. The code for that comes from whichever authenticator app you added your account to. Google Authenticator for example. Open that app and see what number it tells you to use.
