Bootcamp partition lost & missing disk space

My iMac is late 2014, 27", 5k, MacOS Big Sur 11.4


My iMac hanged while the BCA was trying to remove Bootcamp. So now I have a lost the Bootcamp partition and missing disk space.


I was trying this method as mentioned here https://discussions.apple.com/thread/8037379?answerId=32088600022#32088600022 but I keep having the 'sudo: command not found' error.


e.g. sudo gdisk /dev/disk1


I have installed the GPT fdisk download.

SIP is also disabled.
