Weirdly drying

I’m not sure what’s wrong with this foundation as I’m usually a fan of Chanel products. I have oily skin, and I’ve never had problems with foundation becoming patchy or flaking off of my skin. This one seems incredible at doing just that, though. No matter how well I prep my skin, or what products I use to do that, it ends up looking patchy, flaky, and almost crumbles off of my face after a few hours? I was hoping for something more “your skin but better”, and instead got “your skin but much worse” 🥲.
