Activation of Plumsail Workflow Action Pack on subsite not working

I am trying to test the Workflow Action Pack and have successfully installed and activated it on multiple site collections, but I can't get it to activate on one subsite that is the main one I wanted to use it on.
I have uploaded my ULS logs.

Hello @gregm,

Please activate this feature using the following PowerShell cmdlet:

Enable-SPFeature –identity ID -URL

You can find out the feature ID with this command

Get-SPSite https://somesite

I get the below error

Hello @gregm,

Could you try to enable any other feature on the site? Does it work ok or report the same error?
