Powershell Script started by Task Scheduler not working - powershell

Question

So I´ve got a powershell script that checks if a folder was created in a specific directory and then does stuff with that folder
Code:
echo "$(Get-Date -Format g) - Script started" >> C:\bitlocker.log
$folder = 'C:\Path\To\Check'
$filter = '*.*'
$fsw = New-Object IO.FileSystemWatcher $folder, $filter
$fsw.IncludeSubdirectories = $false
$fsw.NotifyFilter = [IO.NotifyFilters]'DirectoryName'
$onCreated = Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action {
$folderNow = $($EventArgs.FullPath)
<do stuff now>
}
Starting this script manually works perfect but running it with the Task Scheduler is not working.
First I tried starting the script directly which shows that the script was successfully started but nothing that happens -Action { ... } gets executed.
I then tried to make a batch that starts the powershell script which gets started by the Task (as suggested here How to run a PowerShell script from a batch file)
PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& {Start-Process PowerShell -ArgumentList '-NoProfile -ExecutionPolicy Bypass -File ""C:\PathtoScript\Script.ps1""' -Verb RunAs}"
but the problem still is the same.
The script starts (Wrote some Output to a file to check that) but nothing inside -Action { ... } gets executed.
Edit: Task Schedular is set to run the script as a user with admin privileges as the actions that do not work need those, writing to C:\ works perfectly fine

Answer 1

Scheduled task action:
Program Script (Use the full path):
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
Add arguments ([NOT]optional):
-NoProfile -NonInteractive -ExecutionPolicy Bypass -File "C:\PathtoScript\Script.ps1" -Any 'other' -arguments 'you need' -should follow

Answer 2

Ok I found my mistake
As #PetSerAl suggested I forgot that the FileSystemWatcher Acts only in scope of that one specific process of the script. The Script has started the Job successfully but after closing the process of the script (aka. the window I started the script in) the Job broke down because it could not refer to FileSystemWatcher anymore.
Adding something simple like:
Do{
$JobExist = Get-Job
} while($JobExist -ne '')
worked perfectly fine
