You’ll have to experiment with the angle of your left hand.
It’s hard to say without seeing/hearing you play but my guess is your wrist is too close to the neck so your left hand fingering don’t have the correct angle so they’re muting the strings.
If you want to record a short video clip and send it to me I can give you more precise suggestions.
