iPhone 14 Pro ‘bug’ when setting up phone

I very recently set up my brand new iPhone 14 pro. I transferred the data over from my old phone to this one, but once that data transfer was complete this iPhone 14 Pro blacked out and was non-responsive. The only way I got it working again was to factory reset it, which wasn’t encouraging given it’s a brand new phone. I’ve logged this with Apple and they’ve informed me they’ve had no reports of this, which I find quite hard to believe. Has anyone else experienced this with the 14 Pro?
