you have a problem in your bdd ...
try change state of content via phpmyadmin (published is state 1)
Problem is: content items' state was and is 1 ("published").
It's the 'publish_down' field that makes the problem:
in table '_content', field 'publish_down' cannot be set to NULL. Thus, CMS correctly takes the items as published, but expired.
See my ealier post:

Good news: I solved the 'post-installation-screen' like so:
1) In phpmyadmin, I manually compared tables '_content' and '_flexicontent_items_tmp'.
All my items have no publish_down date, so table '_content' -> field 'publish_down' was NULL in all rows.
But table '_flexicontent_items_tmp' -> field 'publish_down' had '0000-00-00 00:00:00'.
Neither of those values were accepted by my db, so I entered ~today ('2022-09-30 00:00:00') in both tables, all rows. That fixed the screen.
Bad news: Now all my items are published down. A CMS-user can not change that, because the above mentioned publish_down date can not be removed via CMS.
