Newbie to Blender here. I'm trying to render an interior scene - it's a very simple gallery with two windows. I have added an Image Texture to the 'floor' - this is supposed to be a mid-dark brown wood texture. There are a number of lights in the room, as well as a light outside the windows. (I will attach pictures and the .blend file). In Viewport Shading, the room looks exactly how I need it to look - the colours are saturated and the lights look ok. However, when I go to render it, the floor texture becomes entirely washed out and grey. I have changed the world background colour, I have tried to see if the colours are desaturated, I have changed the image texture to be in the sRGB space - nothing seems to work. I also made a backup and removed all the lighting, and put one spot in the middle of the room to test if my lighting was the issue, and the problem persisted.
I imagine that there's something in the render settings that isn't quite right, but I can't figure out what it is.
Here is a google drive with the relevant pictures and .blend file.
Hope you can help!
