Hi @Aasth
As the log suggests there might be some system events that have caused corruption to the WIPDS. Was the shutdown not done gracefully? As the log suggests, if you have a recent backup of system, you can try to recover using that. However do note that depending upon the last backup date and time some data might be lost.
Also, I see some issues related to access in the shared logs. Was there any manual changes made to the file system permissions or the files under sas-config directory? I would suggest you to check that as well.

My advise would be to raise a SAS Technical support track to help you with the recovery.
