Game hardlocks when someone joins

Whenever someone tries to join a game I host, my game locks up and I have no choice but to terminate it through Task Manager.

Im having the exact same issue.

Two of my friends and I are all having the same issue.

Also having issues like this hosting.

i have the issue of joing a game and then everyone seems to be stuck while i can move and do no damage so im forced to leave

i have same problem. i cant host games. each time someone joins my game - game will freeze. maybe thats why there are no servers i see only ~8 and only 2 have ping under 100ms. and each server is full all the time
well, beta is beta. im looking forward tho. played one game and it looks like fun.

I got the exact same problem.
I missed this thread So I made a new one even though you guys already had 1

If you make a dedicated server 1 can join and than it will still crash, than nothing will happen anymore. Really annoying.
