will not rendor

Hello, the same kind of thing for me...
I need to render a scene for a print project (and I'm awfully late since I spent countless hours trying different settings, resolution, amount of objects in the scene, etc...) The render keeps failing, locally or in the cloud.
I need a 2000x1500 pixels (200 - 300dpi) render.
I really counted on Dimension... 😞
