Error When using Out-EncodedSpecialCharOnlyCommand but only the file and not when using Invoke-Obfuscation.ps1

[KingKDot]

I was wondering why no matter what script I use Out-EncodedSpecialCharOnlyCommand output will always return an error unless im using the full Invoke-Obfuscation. I even tried the examples that are supplied inside of the script and that also doesn't work. I'm not sure if he just stopped updating it and only updated the Invoke-Obfuscation.ps1 but I just want to be able to call it from commandline without having all the text popup and have it take forever.
