That looks like you are not logging in from the official site of the editor. Make sure you are on https://editor.gdevelop.io/.

I even can not create an account.
create account output:
<p>Your client does not have permission to get URL <code>/v1/accounts:signUp</code> from this server. <ins>That’s all we know.</ins>
