I’ve found it pretty straightforward in this last patch as long as you break into the room from the raised walkway from the building next door while in turn based mode and keep the character you want to go in far enough back not to be knocked down by the blast when the door breaks. The pathing isn’t perfect, but at least he’ll actually get up now and run through the door you broke down to get to him (though you might need to get out his way) rather than lying there which he did previously.
This alternative route works yes, but you will miss some immersion giving dialogue.
