I had the same problem and could solve it with re-creating the startup script. Try the following steps:

• delete current process

  pm2 delete nameOfProcess
  

• unload current startup script

  pm2 unstartup systemd
  

• update pm2

  pm2 update
  

• enable startup script

  pm2 startup //copy paste the output
  

• start process again

  pm2 start nameOfProcess
  

• save current config

  pm2 save
