permission denied while execution error

The error message starts like this

A few hours before (25-02-2020: 21:15) it's working properly and then it shows me this error while I'm trying to save my project file in ICEM CFD. And, other products of ANSYS CFX working fine. I don't know what error is this?. Can anyone please let me know how to resolve this error?

Thanks in advance
