After updgrade Network no longer available

Hi, I updated my pve with the common upgrade to 9.2.11, but after rebooting the Networks seems no longer available. It was already on version 9 before since some months and through some updates without any issues. I can log physically on the pve, but it does not appear on the network. Network Interface is unchanged vmbr0 with bridge-ports enp3s0. Any idea how to solve this? Thanks Joerg
