Not sure why this is happening but in shading mode it looks fine but this is what it looks like in Render view mode it was fine till I opened the project yesterday
It seems like you're getting the pink missing texture in the lighting. Most likely you had a world HDRI and you moved the file or the folder and now Blender is looking for the path. Just reload your HDRI and it should be back to normal.
