Invisible Woman's mission: to invade or infiltrate Wakanda, reach the capital, and kill King T'Challa.
Wakanda's intelligence agencies have become aware of the plot and have given T'Challa 36 hours notice. During that time he can prep using all of Wakanda's personnel and resources, and of course his intimate knowledge of the FF. However he cannot leave the royal palace.
At the end of the 36 hours Sue will be teleported to a random location somewhere within half a mile outside Wakanda's border. She has no prep except for a knowledge of her location and the location of the palace.
She kills him and all of Wakanda if she wanted to. Apparently, her shields are strong enough to withstand universal level reality warping from a Cosmic Cube, time altering energy from the TVA, sustained attacks from multiple Celestials, planet busting attacks from Merged Sentry and the Cancerverse, plus she can even cloak herself from a Watcher's senses.

Eh the Sentry wasn't hitting with planet busting attacks...
Though you did forget soloing groups of Mindless Ones, surviving for a few seconds at an Incursion Point (which some have said are where two universes collide), being able to block someone briefly who was beyond Franklin Richards and Squirrel Girl.....
I'm sure I can link Galactus in somewhere.
Thing is, I'm not making this up. It's Marvel doing whatever they want.
But if it is like Hudlin Panther he builds some energy feedback/dampener doohickey keyed to her powerset built from the extensive files he has kept on her for contingency reasons, then depowers her after allowing her to cross the border, and the Wakandan Guard arrest her to stand trial.
