I have an intermittent problem. I use a MacBook Pro M5 with 16GB of Memory). Up until last week I had no issues with Dorico Pro (version 6.2 29/5/2026) . However last week I began to encounter difficulties when I inputted an orchestral score. I had never before created such a large score. First of all I had difficulty in selecting individual parts. For example when I tried to view the piccolo part I would get a black screen whereas I was expecting a white screen without any piccolo music. I have tried updating my OS and Dorico Pro but no joy. Still no music for individual parts.
It sounds like you might have managed to end up with no page template chosen for those layouts in Layout Options. Try going to the Page Setup page of Library > Layout Options, then Page Template, and make sure that Page template set is set to something sensible, e.g. Default Part for your piccolo part, and Default Score for your full score.
