Arrowhead - Unknown command

Rhino Rhino for Windows
1

Version 8 SR35
(8.35.26251.13001, 2026-09-08)

I suddenly encounter a situation where Arrowhead returns the response “Unknown command.”

Restarting Rhino doesn’t help.

I think it happened after the last service update, but I’m not 100% sure.

Best regards,

Restarting Rhino did not help.

Restarting the computer helped.
