UIPath-Assistant - Process execution issue with modifying a txt file


I have a project which reads the email and update the last read time in a text file.

When I run this in a studio, everything good. But if I run via Orchestrator job or UIPath Assistant, its not updating the last modified date in txt file(write text file activity). However, if I update the lastmodified date in Orchestrator Asset, its working good.

I am using community version Studio 2020.4.1 - 5/8/2020
