What is the cube thing in the upper left hand side? Looks like tofu to me but that's an unlikely pairing with steak and potatoes.
You could also just let the print finish. Then open the door before you go out there to gather it. giving it a few minutes to vent. I have minimal experience with resin printing so I don't know how the sunlight would affect it. Putting the printer behind something to block the light seems reasonable as well.
Good luck. You can find these respirators on Amazon. 3m is a common brand.
If you're smelling a strong odor then a respirator would be advised. You need one with an organic vapor cartridge. Surgical mask is doing nothing for you in this situation. Probably easier just to get some good ventilation going though. Or minimize you time around the printer.
