There's really nothing stopping Jason from just teleporting behind CH and snapping his neck. He could literally come from any direction, with no warnings or signs of where he's gonna TP, so it's pretty hard to prep for.
Also, this Jason was given an intelligence boost from Freddy in one of their team ups, which easily allowed him to perceive, analyze and counter a trap set up by a team of trained government agents.
Shift also allows him to disappear and travel short distances unnoticed and bypassing any traps, so he can remain hidden from CH's eyesight and basically phase through his traps.
CH also has no means of countering Jason's heart hypnotizing him into eating it, allowing Jason to posses his body.
