An error that I can't understand

Hello ! Newbie to UE5 here!

I have a project due for friday, and I made my game which works without errors (supposedly I guess), but when I try to build, I have this error:

I actually CAN’T understand what’s wrong, I download Visual Novel 2019, 2022 and still doesnt work.
I tried deleting imported meshes from Internet, and it didnt work either.

Thanks!!
Roman
