Steps to reproduce * Upgrade to macOS 12.6 and restart * Access files on Windows some share, then unmount them * The laptop enters sleep due to inactivity * In the morning, I find the BOOTCAMP volume missing * Console, Crash Reports shows that the UVFS service has crashed at 6:18 AM this should be the cause * Restarting macOS brings the BOOTCAMP volume back * All disk images are 50 GB, sparse APFS case sensitive Other people have the same issue https://discussions.apple.com/thread/254088208 https://www.reddit.com/r/MontereyPatcher/comments/wsg82w/does_anyone_know_what_uvfsservice_is_i_recently/
