Broke PM2, why doesn't it write to the logs?

Question

Node.js

Tell me what could be the problem.
Installed PM2, created a config file, by default, only the paths and names were registered.
I started the projects and everything works, I looked at the pm2 logs all log and it also displays everything and streams the log.
Then I decided to add another project and forgot to cut it, pm2 started swearing at the busy port, in the errors I got 10-15 lines that the port was already busy.
Killed the project forever and rebooted pm2, after that it stopped streaming and writing to the log.
What could be the problem and how to fix it?

Answer 1

$ ps aux | grep pm2
$ sudo kill $PID

And then try restarting
