Throws with \"Authentication Failed\" (V Rising)

Good afternoon comrades.
The real question is, I create a game for myself in solo mode, now, after the patch, even with the online mode disabled in Steam, and I encounter a shutdown after a minute or two with an authentication error (Connection to the server is lost: Authentication error), not I even manage to get out of the tomb, in a solo game without online ...
When playing on servers, I naturally didn’t notice this, but I don’t want to play on servers, because I took the game with the expectation of playing from a laptop in a place where, if the Internet is, then only mobile and ping there "oyaebu".
The Internet is a bit rough and besides the news that the developers "supposedly" fixed this case and did not find useful information on how to fix it, can someone tell me here?
