Page content disappearead

Hi there.
I just put a new website from localhost on to the live-server. it all worked fine until i noticed, that the content of the pages is missing.
i tested the plugins (acitvated and deactivated them) and found out, that the missing content has something to do with beaverbuilder. i deactivated it, activated it new, set the licence key again… nope, doesn’t work. i’m a new user of beaver builder.
wordpress version 5.6… php 7.4. beaver builder Version

any ideas or common knowledge about this topic?
i couldn’t find solutions in the community yet…

best regards

due to some more research I found a solution with using:
All-in-One WP Migration Plugin
instead of copy/paste the links…
