instagram changed color of photos

I just got the IPhone 15 plus and when I first got it I could post videos and photos on instagram but now every time I try to post videos or photos for some reason it changed color and it makes my videos way darker, I’ve tried deleting instagram and downloading it again but it won’t work I also tried restarting my phone and it didn’t work! It’s been bothering me for a while now because I can’t post anything now! Please help
