The process has been in production for over a year and no issues. Recently upgraded to 2019.4.4 version everything was working well for a couple of days and then started failing in areas where Excel scope was used.
Replaced a few excel scope activities with workbook and deployed to production but I do not think that is the solution.
Here is the catch though, the same process works well on Non-prod environments in unattended mode with excel scope. Fails only on the production bot with the “Write Cell: The range does not exist” error. Any help would be appreciated.
