An error occurred while running the crew: Command ‘[‘uv’, ‘run’, ‘run_crew’]’ returned non-zero exit status 1.

I found the the root cause.

Ridiculously, I use crewai create crew latest-ai-development and the .env file use model=azure/gpt-4o instead of MODEL=azure/gpt-4o, it failed, but there is no error information in crewai framework???
