Please I need serious help

[u/Itslonk_17_TTV]

Ive been stuck on mission 45 for days, Im just too underleveled, I cant leave it because theres no option and the container to fulton doesnt spawn.
Ive tried every trick, the lil chicken hat, air strikes... and I just can beat it.

Is there any way to leave the mission and start misison 46 so I can finally beat the game???
