Removing Bootcamp failed, storage is gone?

[LK LAW]

Well I have a fun problem, trying to remove my bootcamp partition via the bootcamp utility failed. Now the lost space is nowhere to be seen. Any idea how to fix this without nuking my install and reinstalling macOS?

/dev/disk0 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER

run diskutil list (again, because sometimes the disk identifiers can change)

The first command deletes the KernelCoreDump partition, which shouldn't be there...
The second command will grow your APFS container to the end of the disk.

diskutil eraseVolume "Free Space" NoName disk0s4
diskutil apfs resizeContainer disk0s2 0

Note: The 2nd command will freeze your system as it resizes, don't power off your machine let it finish.

There’s no disk0s4, do you mean disk0s3?
[doublepost=1536310436][/doublepost]I removed the kernelcoredump, resizing the disk gives me the error “-69582: one or more of the given or implied APFS Volumes are locked”

Edit: nvm managed to fix that
Edit 2: fixed it thanks!
