I have had this issue 4 times now as well in ~50 games. Other players reported it too(chat works for some odd reason) so it is definitely not uncommon. UI & camera freezes, sounds play and your ship sails out into the sunset. Can't exit the game, after manually killing it with task manager, every time I load back into the same battle the issue is there 100%. Someone said that either zoom mods or the score timer might be causing it. Well it is not the score timer, I disabled that and still had the freeze. I'm not planning to play without a zoom mod for god knows how many games, sorry(WoT included it into the game after 5 years so fingers crossed for WoWS 2021 smh...) and my guess is that it isn't causing the issue either. I'll just attach the log.
