Fresh install of Monterey using MLOC.
Monterey started taking a long time to shutdown so I ran First Aid.
I have MLOC installed on Mojave SATA SSD bay 1 and Monterey on PCIe SSD slot 4 (need riser cable for slot 2)
The system volume and the physical disk are OK. I get the above error when running first aid on the APFS container volume. There are several snapshots that are corrupted, is that the reason for the error code or do I need to repair in Recovery or possibly wipe drive and start over?
