Hi Troy,
you may need to set the execution policy to Unrestricted in order to make it work. Also check the Options -> Dynamic Folder page to see if you are referring to the PowerShell 7 executable:

The latest version of Royal TS now supports setting environment variables instead of using replacement tokens. Check this thread:
With environment variables you could sign your scripts you place in the dynamic folder/credential scripts.
Let me know if this helps.
Regards,
Stefan
