I received the same initial error message. I quickly copy and pasted the message into a google search and found this post. I went to follow the instructions for the top answer on this post, but google wouldn't let me log in or there was some weird loop of logging in and then selecting which google account to log in with. I then navigated back to my developer account and then my new project was created and selected in the list of projects. Note that, unlike the original poster, I had already had three existing projects, don't know if that makes a difference, but I'm sure it's possible. Here's a pic so you may see exactly what I'm referring to. As you can see, the project I was trying to create is called 'Neighborhood Map Project' and is selected from the project list dropdown. I feel like I dodged a bullet here and saved myself two hours of fiddling around and I wanted to share my experience with you all so that you may quickly resolve your problem like I did.
Cheers
