Keyboard Issues – Fix Microsoft Sculpt Keyboard Unresponsiveness on Mac

I have a macbook pro running OS X v10.13.6 and am using the microsoft sculpt keyboard with it. The keyboard works but would become unresponsive intermittently. This is the setting I see in System Information:

I did some search and found some related links but:

• This one says its completely unresponsive which is not what I am experiencing
• This one also does not help
• Over here I can see 10.13.6 is not listed but am guessing that's just because its outdated and the info needs to be updated
• This does not help
• This too did not help

I have listed above links as sometimes I would get a downvote saying what have you tried – so listing them to show I have done some due diligence and unable to resolve the issue.

Further I have turned bluetooth off on my mac to avoid any interference (not that it should matter)

The Keyboard System Assistant (system Preferences -> keyboard -> change keyboard type…) shows this:

Does anyone know how to fix this issue? Thanks
