[Bug Report] Unable to process request - while running custom commands and skills under .claude

Bug Description
[Bug Report] Unable to process request - while running custom commands and skills under .claude I get a 400 API error that the command is empty but it is not. And claude code crashes and keep showing me the same message.

I have logged out a couple of times. It works fine in the other terminal windows and repos only this specific repo runs into this probelm.
