Bootcamp no longer showing up at start up (holding option Key)

Resizing Windows partition is not officially supported. If you third-party tools, it causes problems on 2014 or older Macs which run Windows using legacy BIOS mode, because the MBR and GPT are no longer in sync. You are lucky that you have not lost your data yet.

Post the output of

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0

from macOS Terminal. If you do not have permissions, temporarily disable SIP in Local Recovery using csrutil and retry the commands.

You need to temporarily disable SIP by booting in Local Recovery and using csrutil. It cannot be changed when booted normally.

After you boot into Local Recovery holding Command+R at boot, click on Menu Bar -> Utilities -> Terminal.

You are missing a "/" between '/dev' and 'disk0'.

Type

sudo<space>fdisk<space>/dev/disk0

where <space> is the space character. Enter your password when prompted. It will not be echoed back to you.

studo gpt -vv -r show/dev/disk0

Correct: sudo gpt -vv -r show /dev/disk0

sudofdisk/dev/disk0

Correct: sudo fdisk /dev/disk0

sudo gpt -vvr-rshow/dev/disk0

Correct: sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev /disk0

Correct: sudo fdisk /dev/disk0

sudo gpt -vv -r show /dev /disk0

Correct: sudo got -vv -r show /dev/disk0

Your command you type is all incorrect. That’s why the solution is not working. Remember to check all spaces. Post the output again with the correct command.
