When you run the n8n start command does the terminal go back to a normal prompt or does something else happen? We would typically output something if you use n8n start, What version if n8n did you upgrade from?
Was using PM2 to run the app, later found the app is not working then removed pm2 and run using n8n or n8n start. But everytime I do that there is nothing coming it is just going back to normal after few sec. The strange thing is this is happening on 2 different servers and on my local Mac it is working perfectly fine.
