I needed to resize my APFS partition to install Asahi Linux.

The Asahi installer couldn't resize the partition due to some orphan inodes or something.

Rebooting into Recovery mode and using Disk Utility (GUI) and diskutil (CLI) didn't fix the issues.

But `fsck_apfs -y` did the trick. I had to first do `diskutil unlock volume -nomount` as it was an encrypted volume.
