Unknown error

Troubleshooting and Resolution Steps

1. Preserve the scene. Save the log files and try to record the situation at the time of the failure as much as possible. (You can analyze the stack information using some third-party tools or by using jstack [PID] > jstack.log.)
2. If there are logs of other error codes before this error code, check the records of that error code first.
3. Check if there are any errors in the configuration files.
4. If the error was introduced by modifying the code, try rolling back to the previous version.
5. If none of the above steps resolved the issue, create a minimal Demo to reproduce the problem, then report the issue on the GitHub Issue Tracker.
