I have tried using DAX contains strings, adjusting the filter well but all seems returning error or nil result

Solution

Create a Measure similar to:

Keyword count = 
  IF(
    ISFILTERED(Keywords[Keywords]),
    SUMX(
      DISTINCT('Keywords'[Keywords]),
      COUNTROWS(FILTER('Activity', CONTAINSSTRING('Activity'[Activity], [Keywords])))
    ),
    COUNTROWS(Activity)
  )

Add this new measure to your visual as a Visual Filter, and set it to is not blank, in the Filter pane.

Suggest your keyword list is non-plural (gift instead of gifts as an example).
