xbar not starting on macOS Ventura

I just did a fresh install with brew, running version 2.1.7-beta on macOS Ventura 13.0.1.

When I start xbar, it asks for the Automation -> System Events permissions, but nothing else apparently happens: No app window opening, nothing in the status bar.

There's three processes running for xbar, visible in the Activity Monitor:

• data:
• xbar Networking
• xbar

Running it in the Terminal shows

❯ ./xbar
xbar v2.1.7-beta
2022/11/29 11:28:40 checking for updates... (current: v2.1.7-beta)
2022/11/29 11:28:40 updates: passive true
2022/11/29 11:28:40 updates: AutoUpdate false
2022/11/29 11:28:41 update: you have the latest version

Any help with this or info how I can further debug this is appreciated.
