Could you kindly grant me access to your Joomla administrator area so that I can investigate the issue you're experiencing? Prior to providing access, please ensure that you have backed up your site. Additionally, it's important to note that providing login credentials is entirely voluntary on your part; we respect your decision either way. However, if you do choose to share the login details, it would greatly expedite the resolution process. Thank you for your cooperation.

There was pages before? And do you have backup of your site?

If you start a new project then you will see the empty on the pages listing area. You have to create pages for yourself. Thanks

Yes, It will work. But, You should use quickstart pack instead of fresh Joomla.
