Mounting 65” tv on panel construction wall with metal studs 24” on center
Depending on your TV mount style, I would simply drill extra holes in it and run four to six sheet metal screws through into the studs. 8 to 12 sheet metal screws will easily carry that television. This assumes that it's tight to the wall and not an articulating arm style mount

Size the holes in the mount so that the screws slip through freely, and be sure not to overtighten so you don't strip the threads in the studs. Just snug them up.
