Powershell Start-Process works but not from .ps1 script

If I paste this into Powershell blue window it runs fine and launches the program 

Start-Process “C:\Program Files (x86)\Engine Pro\engine.exe” -ArgumentList "#21#”;

but if I try to run the same command in a script, run.ps1 script, that launches from a scheduled task in Windows, it does nothing

PowerShell.exe -windowstyle hidden -NoProfile -ExecutionPolicy Bypass C:\run.ps1

Does it have something to do with the -ExecutionPolicy Bypass? Do I have to have an Execution policy in the script as well? I really don't know what that is. I know what -windowstyle hidden is but -NoProfile -ExecutionPolicy Bypass I'm not sure why that is there, just found it on another page, but it's all working except for the program launching from within the script.

Thank you.

Your command uses Unicode (non-ASCII) double quotation marks; unless you save your *.ps1 files as UTF-8 with BOM (or as UTF-16LE), PowerShell will misinterpret it. - mklement0
Depending on your PowerShell Version (below 6/core) the default is -Command not -File, so you may need to use PowerShell.exe -windowstyle hidden -NoProfile -ExecutionPolicy Bypass -File C:\run.ps1 - user6811411
The whole script works with the " " on everything, but when I try to launch a program from within the scritp it just does noting. Im using " " and editing the file with coding program ATOM 1.33.1 x64. Adding -File did nothing. I thought it might be BitDefender but I switched that off and stiff the program is not launching. I tried launching notepad.exe from the script and that doesn't launch either. Not sure what's happening. - Kurt Lane
Stupid me, It was the & symbol. Ive seen it on hundreds of threads already. & Start-Process "C:\Program Files (x86)\Engine Pro\engine.exe" -ArgumentList "#21#"; worked, Took a while it figure it out. Thanks everyone - Kurt Lane
