Lost APFS partition after resizing partition in windows
Your partition table seems screwed:

Your first partition on disk1 is a Windows Recovery partition, the second is an EFI partition. Then either Microsoft Reserved (E3C9E316-0B5C-4DB8-817D-F92DF00215AE), Basic data (EBD0A0A2-B9E5-4433-87C0-68B6B72699C7) or Windows Recovery (DE94BBA4-06D1-4D40-A16A-BFD50179D6AC) partitions.

But the hexdump of block 335874048 (the first block of the 6th partition) looks promising:

...
0000020 4e 58 53 42 00 10 00 00 29 ea 22 01 00 00 00 00
...



4e 58 53 42: magic string of an APFS container  
00 10 00 00: APFS block size: 4096  
29 ea 22 01 00 00 00 00 APFS container size in APFS blocks: 19065385 (=152523080 512-blocks)

After re-arranging the Bytes 29 ea 22 01 00 00 00 00 > 00 00 00 00 29 ea 22 01 > 00 00 00 00 01 22 ea 29, you can get the decimal value here: 




The sixth partition obviously has the wrong type!

The partition type has to be modified with gpt then:


Disable SIP in Recovery Mode (the recovery system version has to be 10.11 or newer)
Boot to your external drive or Internet Recovery Mode.
Open Terminal and get some details:

diskutil list
sudo gpt -r show /dev/disk1

remove the 6th partition:

sudo gpt remove -i 6 /dev/disk1

restore the same partition with the proper type:

sudo gpt add -i 6 -b 335874048 -s 152523080 -t 7C3457EF-0000-11AA-AA11-00306543ECAC /dev/disk1

check the APFS container

diskutil verifyVolume disk1s6

Enable SIP in Recovery Mode




The partition layout is still uncommon since macOS usually requires an EFI partition as first partition. 

The non-default layout may prevent firmware updates in the future!
