Does Tailscale v1.41.62 block access to network interface for VPN Server Package on Synology DSM 7.2?

The topic almost says it all … since I updated manually to DSM 7.2 (-64561) VPN Server does not work parallelly to Tailscale on at least two of my Synology NAS (718+ and 720+)?
Before applying the above mentioned DSM update manually this worked like a charm.
But after the update the package (Syno VPN Server) itself is running, but under “general options” i cannot choose any network interface or account type - it is just empty.
Stopping VPN Server and restarting or uninstalling and re-installing did not solve the problem.
Stopping Tailscale ended in first Syno system-hung-up for 6 years. So after Reboot I did not delve further into the problem and decided to ask in this (and synology) forum.
I was hoping to let both services run parallelly (as before) to have a “backup”-VPN on built-in- Syno Services.
Does anyone have a clue or suggestions? Thanks in advance…
