Did the system upgrade to OMV 5.6.25-1, and was prompted to Apply config changes afterwards. Apply failed, but afterwards all of my SMB shares were unavailable. Tried clicking Revert, but no change. Tried restarting, getting red text in systemctl status smbd.service for journal entries. Reinstalled 5.6.25-1, still failing. Additionally, from what I'm seeing in journalctl -e Samba is looking in /var/lib/samba/usershares for .conf files matching the names of the shares on my system, and it doesn't find them. I did go there and confirm that the directory is empty.
To be clear, the OMV UI still shows all of the SMB shares actually there and properly configured. Any change I make that does not involve SMB works fine and the apply takes. Any change to SMB fails with the below error. Had to go through PasteBin as it seems the error itself exceeds the permitted word count.

Any help would be appreciated - it's not critical yet, but that's just because my wife hasn't tried to access it, and while I can get at her files, I'd rather not. If it matters, specs are Ryzen 9 3900X, 128GB RAM, lots of storage in ZFS. Everything except SMB works fine, including KVM, Docker, and NFS.
