Hey there leonefromvictoria,
Thanks for reaching out to the Apple Support Communities.
Just to confirm, are you trying to access your Apple ID from the Settings app? If so, can you provide a few more details on what you mean when you say nothing happens? For example, does the Apple ID settings page never load, or do you only see a blank white screen?
Also since the issue started, have you tried restarting your iPhone? If not, while this may seem like a simple step, restarting your iPhone can often resolve many unexpected issues that may occur. For steps on how to restart your iPhone, check out this link here: Restart your iPhone - Apple Support
