[2021] textures flickering

Hi,
Since yesterday I have a problem with textures in Anno 1800. The problem appeared after "discovering" the next class of inhabitants.
There is a texture flickering effect with every configuration of the graphics settings.
I tried turning off anti aliasing and changing the texture level (from Low to Ultra).
I also tried changing the DirectX driver to version 11 and 12

I reinstalled the game and I have the current drivers for my graphics card.

Hardware configuration:
CPU: Intel Core i7-9700 @ 3.0Ghz
GPU: GeForce GTX 1660 SUPER
RAM: 16 GB
SSD: 25 0GB
OS: Windows 10 Pro
