Clogged load of mess

Good morning, been 3d printing for a while at work but bought a K1 Mx for home and had my first problem

1/2 way though a print looked to check everything ok and was greeted by this

whats best way to remove this and check whats wrong, looks like something split behind in orange , ive used a no flame heat gun to melt away some of it as don’t want to cut or bend anything
