Task Manager - Powerhshell not launching MS Access - powershell

Question

I have come across a very strange situation and I have not a clue as to why this bug is occuring.
In short, I have a powershell script that if I run manually works 100%
I have set this as a scheduled task in Windows Task Manager and the event launches, runs the SQL element of the powershell script so I know that the issue doesn't exist there. However, within the powershell code I have it open a specific MS-Access database and this is not working.
shorter version, - Works when not automated, automation works but not MS-Access
I am confused, I have included the code can anyone see anything untoward?

The automated task is simply written as

Add arguments (optional) = C:\scripts\ComplianceLimitOrderTestRunTime.ps1
I had wondered if this was an execution policy issue but it is set as unrestricted.
I cannot understand why this would work as a manual execution but not as an automated execution, any one shed any light on this?
