It seems on your earlier installation had PHP 8.0.0 with which builder isn't compatible right now. And some templates aren't accessible is because they are Pro Templates which will be available once you buy one of our Pro Plans.
Since you have managed to solve the issue on a new installation, should I consider closing this topic now.
Do let us know for more.
If you like our support and products, tweet us at joomdev and let the world know about it.
Regarding Pro-Templates, I chatted with your support yesterday because I can't select a page from a pro-template (Message "Your subscription has expired..."). He couldn't help me any further and asked for the email with the access data so that you can check this.
