Hello,
You can’t log in because the database is showing an error.
I’m afraid it’s damaged. There are several posts about this issue (Database: ERROR (spawn error) but not a quick solution.
If you rebooted recently, check the status of your database service. It may be it’s not running. Then try cryosparcm stop; cryosparcm start to stop the instance properly and start everything again.
Good luck with this…
Juan
