Cruxia is a much different case.
You have to find her within each passing hour. Failure of finding her results in her being outside your door and several eyes surrounding you before she swallows you whole.
Either before Thorne’s stream starts or after the sign pops up, find Cruxia and then get to Thorne’s stream and click on the heart several times to keep Thorne occupied. If you run out of time to get to Thorne’s stream, she’ll put up the technical difficulties screen on every camera like with how Paranoia corrupts the cameras in the first game when the Betamax tape runs out before appearing in the office and swallowing you whole. The only other saving grace of avoiding Thorne’s wrath when that happens is to go to the vent and hold it until Elina catches you or if you decide to quit the night by hitting the “escape” key and starting over.
