I've been experiencing this exact issue for nearly two years now. Multiple support tickets were submitted, but unfortunately all received only automated responses with no real assistance. As a workaround, I purchased a custom domain and set up email forwarding to use with a separate account. Fortunately, this account worked perfectly for enrollment from day one. If anyone from Apple is reading this and has the ability to help, please do! I'd genuinely prefer to use my personal email address directly in my main account rather than having to maintain a separate account through an email forwarding service

Hi! Sorry for the necromancy but this issue still persists in xcode 16.4 and xcode 26 beta 6 For now my choice of a workaround is to play with that "Show live issues" checkbox Such a frustrating bug for someone who tries to learn swift 🫩
