Hello,
Even on a completely new and clean Windows 10 with the latest compilations without any Antivir (only Windows Defender) unfortunately, Wildlands every time after trying to exit to the main menu, from any other game mode in addition to the main campaign, first goes to Uplay and re-loads the game to the main menu. It looks like this is just how this game was constructed :). Until now, I was convinced that this is a KIS problem but now this action is done in the same way without any error. The working of the game is the same as with KIS, but without error, which reported Sib3riX above. So it looks like it's just the design of this game and that's all. Problem with Wildlands and Uplay and not KIS or EAC. Sorry for an unnecessary problem and thank you for your support.
