Playlists disappeared after latest update?

OK, here goes!

I have a single server, with a 13th gen Intel i7 processor and 128GB memory. On this I run Proxmox VE (latest release). In Proxmox I have a number of Virtual Machines:

1) Truenas Scale - (4 vCPUs, 24GB RAM) this has a PCI Host Bus Adapter passed through in hardware from Proxmox to the VM. Attached to the HBA card are two Seagate 18TB drives, configured in a ZFS mirror pool. The 18TB is split into two volumes - "Media" and "Users". Media contains the music (in a dedicated folder), along with movies and photos. Both volumes are shared via CIFS/SMB
2) Ubuntu Server 22.04 LTS - (6 vCPUs, 32GB RAM) The sole purpose of this VM is to run Docker containers. There are 24 containers in total, including Minimserver, Plex, Frigate, MQTT-Broker, Immich, Portainer and others
3) TP-Link Omada Controller (Running as an LXC container with 2 vCPUs and 4GB RAM)
4) Home Assistant (2 vCPUs, 8GB RAM)
5) Windows 11 - this is generally left shutdown and only booted for certain tasks
6) Ubuntu Server 22.04 LTS (4 vCPUs and 16GB RAM) Running nextcloud - but never actually used.
7) Ubuntu Server 22.04 LTS (4 vCPUs and 16GB RAM) Running ZabbixNMS - not yet configured this fully.

I've already tried shutting down any docker containers that could possibly be writing to the Music folder but something I'll be trying today will be to shut down everything except Truenas and the Minimserver container.

Hope that covers it.
