Hey DiegoAce! Welcome back to the forums!
My first suggestion would be to try adding another collision volume to the actor that only blocks Pawns and does not simulate physics, and turning any other collisions on the actor to ignore pawns and simulate physics. If you want it to ONLY block the player, you need to make another collision channel called “Player”, give it to the player collision, and have it default as a pawn would be set up. 
This should give you the desired result.
