Sonos - "Roon lost control of the audio device" after Sonos Update [Resolved: Update Sonos Firmware]

Can’t connect to my audio device via Sonos stream (via AirPlay it is possible):
“roon lost control of the audio device”

Same Issue like here:

Configuration details:
• Roon R.O.C.K on PrimeMini with an Intel i7 and 16 GB RAM
• Remote(s): Macbook (MacOS 12.6.4, Intel i5, Roon build 1244)
• Networking details: I’m using two routers: One Router (FritzBox 7430) connected to the internet and one attached router (Linksys) to the FritzBox where the Roon Core and the Sonos Playbase are plugged-in with RJ45 cable. I use DHCP at the Linksys Router - also sometimes VPN, but the issue persists when VPN is off.
• Audi Devices: Sonos Playbase and Sonos Sub
• Library details: Qobuz streaming service, about 500 tracks as well as on local album
