Xcode 11.3.1 gives me No image found at path referenced under key CFBundleIcons appIconXX error when I try to validate my app

Question

I am about to launch my ios app but when I do a product>archive>validate app I get the errors "gives me No image found at path referenced under key CFBundleIcons" for all my icons AppIcon20x20 AppIcon29x29 AppIcon40x40 AppIcon57x57 AppIcon60x60 etc

But I have added all icons in the AppIcon folder, also doubled checked that they are in the correct size and that all is .png But I keep getting the error.

My icons shows up in xcode's menu and in the simulator so its really weird
