Time working on the mute (striking down with the pick and palming the strings at the same time) as a separate technique.
Then added back to the strum.
Once you’ve done that you may want to try using this five minute practice session to work on it some more: https://realguitarsuccess.com/lessons/c-g-with-mute-strum/
But only after you’ve worked on the technique by itself.
