Describe the problem
0.14.5 release looks potentially broken

To Reproduce
Steps to reproduce the behavior:

  1. Start netbird daemon 0.14.5 on a clean linux vm
  2. Wait for unix socket to appear
  3. Run netbird status
  4. See error

Expected behavior
netbird status should return Daemon status: NeedsLogin, netbird daemon should not panic

Additional context
Reproducible using NixOS test on aarch64 and x86_64, here are the logs: https://logs.nix.ci/?key=nixos/nixpkgs.223194&attempt_id=1560fe63-abee-4393-9a0f-7ea337bbc37c
