I tested importing on my test site and it imported fine. It did take longer to import due to the images but that was expected.
I suspect that the web host is either preventing the increasing of the PHP max execution limit or hard limits it to some amount. This is something Connections and other plugins due dynamically to prevent these types of issues.
The import happens in batches of 100. Another user had a similar issue and I hard to force a limit of only 10 per batch. I suspect doing the same for you will help.
As for the email, use any random fake email address since this is just for a temp admin account which you’ll delete after we’re done. Just create a username and password with a fake email. Post the login back here as a private reply.
