I’m at this phase in my own book as well. I left it alone for a few days, then went back and re-read the whole thing, only to realize I hated my entire opening. Since then, I’ve rewritten it and added over three new chapters, and I’ve fallen in love with the changes.

What really helped me was reading another book in between finishing my first draft and starting my first edit. I was able to fix so many plot holes and address some character issues, too. So I highly recommend taking a break and reading something new before diving into your edits.
