The game seems to hate overlays. Steam and Uplay don't cause issues, but a lot of other software, such as third-party screenshot makers, antialiasing utilities like MacType, cause crashes on startup. Disable or close them beforehand.
This issue comes from using the programm Actual Multiple Monitors for multi monitor setups. This can either by fixed by simply closing the program or setting the Anno2070.exe as an exclusion in the Window Settings Tab of Actual Multiple Monitors.
