Thanks @szymczyk, i had the exact same Problem (Fatal Error: UIViewControllerRepresentables must be value types:_). The problem was, that I was subclassing UIViewControllerRepresentable as a class instead of a struct. I'm not quit sure why this worked until updating to iOS16 but using struct does fix it.
