i have the same issue, i can connect and the game works as it usually does for about 30 seconds then my attacks or interactions with NPCs stop working but i can stil receive dammage, and a bit after that it usually disconnects me, i ran the diagnostic test that can be found on the support section, and as i do not understand the results i will attach it to this post.
i hope this problem can be solved for the few of us that have it, because as it is, the game is unplayable.
