I am trying to use the Google Calendar API in one of my projects. To do this, I need to configure OAuth access on the Google API console. But when I create the consent form (which is required to use OAuth), I get a meaningless error message:

The translation is as follows:
There is a problem. Check your details and try again. If you have no details, the problem can be solved by itself. In this case, we recommend that you wait and try again later.
I set the email address and project name. Optional fields are left blank.
So far, I have not been able to solve the problem. I tried to wait a few hours / days. I tried three different browsers. I also tried to contact Google support. All without success.
