At that point I would try deleting everything Uninstalling the game and re-installing but I'm sure you tried that at that point I would run out of ideas and go back to the stable version to play. Not sure why it would keep doing it even after doing all that. If it keeps not working I hope someone else can give you an answer I tried XD

I haven't run into the issue of not connecting but I was told before going to experimental you need to delete all old save files from the base game before you switch to beta if you haven't maybe that's what is going on?

this happened to me as well the one running the server as host cant log out before anyone else or this bug will happen and you cant loot. to fix it you have to start a new game server.
