In my Macbook pro (2016 touch bar), previously I installed Windows 10 and upgraded to creators version. In Windows session, in the bootcamp "Restart in macOS…" option is returning "Could not locate the macOS boot volume." error.
When I ran the gdisk tool (based on this thread answer) to list the partition details, I see my mac partition (#2) has FFFF code (seems to be unknown)
c:\Temp>gdisk64.exe
GPT fdisk (gdisk) version 1.0.3
Type device filename, or press <Enter> to exit: 0:
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.

Any help to boot into macOS?

You can still boot the macOS partition right? You can hold down Alt/Option upon startup and it will give you a list of bootable volumes. Choose Macintosh HD (or your macOS partition) to boot it. Once you're done, you may wish to change the default boot to macOS in System Preferences -> Startup Disk. To boot your Windows partition again, hold Alt/Option upon startup and choose BOOTCAMP (your Windows partition).
If you have any other Bootcamp questions, let me know. Cheers
