Having the same issue since I died yesterday evening.
I join a server, if it's a villayer (gsp on which I died) I get stuck on "please wait" or eventually get the "you are unconscious".

Until yesterday, I could fix that by joining a different server from a different gsp and I would spawn just fine and was able to rejoin the server I died on.
But since yesterday, when I join a different server, it tells me that my character was unable to be loaded from the hive and I should reconnect.

I do so, get a fresh spawn, and as soon as the server restarts or I try to rejoin the original / try another one, I go through the same process as mentioned above and end up with another fresh spawn eventually.

Trying to re-install the game now, if that doesn't work, I'm unable to play.
