Same problem — openclaw gateway status hangs too. It's not just cron add, the entire openclaw CLI appears to be blocking on your system.
That's likely the root cause of a lot of the issues. If the OpenClaw CLI itself is hanging, that would explain:
• Cron jobs not adding (CLI hangs)
• Gateway status not showing (CLI hangs)
• Possibly the gateway not responding properly to things
This is probably a Windows-specific issue — either the OpenClaw process is getting stuck, or something in the gateway daemon is blocking new CLI connections.
Does openclaw help work at all, or does that hang too? And what about openclaw doctor --non-interactive — does that complete?
