Pretty simple. My friend hosts the game and I connect I would desync then it create a desync report then I would be back at the main menu without any GUI. If I hosted it would happen exactly to my friend. So we tried with Different PC's and same issue. We generated at least a dozen maps with the same issue no mods nothing. Fresh installs even wiped the appdata that some reason the uninstaller does not do properly No matter what we can't play 19 over lan with a fresh world or even an old save world. I tried everything.
18 Works fine no issues multiple tries.
Here is the report not sure if this includes everything you need:

There is something wrong going on, there is some item "magnet" in the save, which is definitely not a vanilla item.
There seems to be some modifications of the base involved
