I have exactly the same error as you! After 5 mins, I need to restart the game. If I am in match I dont get disconnected but after the game ends, I need to restart the game, which is really, really annoying. And since it isnt on my end, I cant do anything, or, if I can, I dont know what to do.
I have this error since season 1, and stopped playing because of it. Restarted playing it this season, with a couple friends, but the constant crashes make it so unplayable its unreal.
I dont know what else to do at this poing..
The UO tool log in here goes attached, hope it might shed some light on this issue.
