Interestingly, GCP now appears to be available to individuals in Europe. It wasn't like that before, no idea when that policy got changed. Before, GCP wasn't even a consideration compared to AWS (which always handled that).
I think this is what tripped me up before. I closed my business years ago but it was completely impossible to get Google to fix this. Now it fixed it "by itself".
Just a warning to everyone before signing up with your main Google account :-)
