I can't play the DLC due the graphic problems: i don't see the units

I recently bought the new DLC but unfortunately i can’t play it due graphic problems during the cinematics of the first two missions. Graphic looks very low and there aren’t units. After the second cinematic (the first after the prologue) i can’t play anything because the screen turns into black.
I made a video to show what happens.

I tried to reinstall the game several times but there’s not solution.

My specs are Rtx 4080.

The other campaigns are ok and i didn’t find graphic problems.

It can’t load any of the Chinese assets? All the buildings are Greek!
Maybe some DLC validation error?

I finally resolved the main problem. I had some problems with updates on my desktop.
Thank you for support.
