Bootcamp Stuck on "Partitioning Disk"

I tried to get Bootcamp installed but after it got to "Partitioning Disk", it suddenly slowed to a crawl. I've left my MacBook on throughout the night and it's still barely made any progress when I woke up. Disk Utility shows that although there aren't any new partitions, the free space is SLOWLY (and by that I mean slowly) getting smaller and smaller, which probably means the partition is slowly being created. Is there anything I can do to fix this/speed it up?

Hmm, nothing really happened after I ran this, and fsck_apfs -s -o -y /dev/rdiskN (N being the APFS Container of course) still gave me the same results as the first time I ran it. When I run diskutil list internal in recovery mode curiously, it gave me a different output than what I got outside of recovery mode. Should I try this again but with the disk with APFS I got in terminal outside of recovery mode (Disk 1) or the one I got during recovery mode (Disk 2)?

Another thing, by "diskutil unmountDisk APFSContainerDiskHere", did you mean something along the lines of "diskutil unmountDisk Disk2"? Thanks for the help regardless!

Nope. How should I terminate the process?

I tried to use bootcamp again after updating, but it got stuck at the same process again. Any fixes?

couldn't take screenshots during recovery mode, so this is the best I've got!

By "boot normally", do you mean boot out of recovery mode? And how should I cleanup the snapshots?

In your previous screen shot it shows snapshots 1 of 2. This shows only 1. Was the other one deleted?

Hmm, I'm not sure. I haven't done anything to try to delete it though.

This may be correctable.

Boot into macOS Recovery - About macOS Recovery on Intel-based Mac computers - Apple Support
Click on Utilities -> Terminal, and run
- diskutil list internal
- Find the APFS container
- diskutil unmountDisk APFSContainerDiskHere
- fsck_apfs -s -o -y /dev/rdiskN where N points to the APFS Container
Reboot and retry BC Assistant

Huh, it shows the same thing:

Snapshot for disk1s5s1 (1 found)

    NOTE:        This snapshot limits the minimum size of APFS Container disk1

I ran sudo fsck_apfs -n -l /dev/rdisk1 again as well just to see if it's different, and it is:

** Checking the container superblock.
   Checking the checkpoint with transaction ID 16379753.
** Checking the EFI jumpstart record.
** Checking the space manager.
** Checking the space manager free queue trees.
** Checking the object map.
** Checking volume.
** Checking the APFS volume superblock.
   The volume Macintosh HD - Data was formatted by newfs_apfs (748.30.63) and last modified by apfs_kext (1677.120.9).
** Checking the object map.
** Checking the snapshot metadata tree.
** Checking the snapshot metadata.
** Checking snapshot 1 of 5 (com.apple.TimeMachine.2021-07-09-134700.local)
error: btn: invalid value (3388, 20)
   Snapshot is invalid.
** The volume /dev/rdisk1 could not be verified completely.

now it says that there are 5 snapshots, weird!
