Ok guys, just in case this helps any of you I am going to post this from my own thread:
"Playing" on GOG. Downloaded patch 2 last night (I guess it was patch 2, it was not annaounced anywhere, but it was 2,5 GB of data) and the game is not running. After I try to run the game I get three possible outcomes: 1) CTD on startup 2) The game loads but with no audio 3) The game takes around 15 min to load.
EDIT: Was able to "solve" this issue by uninstalling the game, completely removing any files connected to it from my PC, and then installing the game to a completely different location on a completely different HDD (which is not SSD unfortunately unlike the previous one). Veryfing game data nor reinstalling the game to the same location did not help.
P.S.: I had remove even my local saves luckily the ones that got downloaded from cloud worked. Hope this helps.
