Hi Bowen Wang,
It seems like the issue you're encountering is related to a Fluent license problem, as indicated by the error message in the log files. Here are a few steps you can take to troubleshoot and potentially resolve this issue:
Check Fluent License Configuration: Make sure that your Fluent license is properly configured and valid.
Restart License Server: If you're using a network license server, try restarting the license server to ensure that it's running properly and accessible by Fluent.
