Baby suddenly refusing food

My little boy will be one in a few weeks. He was an absolute joy to wean, would eat anything and was really up for it. I did a combination of baby led weaning and spoon feeding. He went through a phase about a month ago where he wouldn’t eat off a spoon so did mainly finger food but now he is having a mouthful then turning his head away from things / throwing food on the floor.

Any advice to get him back interested in food and eating again like before?
