The 20-year-old had high hopes of challenging for the podium in the giant slalom yesterday.
But that dream was crushed within moments as Robinson made a series of mistakes on the top section of the course and could not recover.
She fought hard just to stay on her skis and eventually completed the course in 1min 0.55sec, finishing 2.99sec off the pace set by Sweden's Sara Hector.
Robinson posted the 25th-fastest opening run to guarantee a top-30 start for the second run later in the day, but she was too far back to contemplate challenging for the podium.
Her second run of 1min 0.27sec lifted her to 22nd-equal.
Hector continued her fine form in the second run to win the gold medal, Italian Federica Brignone claimed the silver, and Switzerland's Lara Gut-Behrami the bronze.
The opening run had plenty of drama as Robinson first watched reigning Olympic champion Mikaela Shiffrin crash out after only a handful of gates before last season's world cup champion, Marta Bassino, followed suit.
The Kiwi's first three turns out of the gate on her opening run were poor as she battled to get to grips with the conditions. Her outside ski failed to grip into the snow and the aggressive Robinson had to correct herself all the way down the hill.
Afterwards Robinson indicated she had an equipment problem.
"Struggled a bit with the equipment and getting grip on the snow," she told Sky Sport after the first run.
"It was a bit of a struggle and I couldn't find anything the whole way down."
Co-coach Chris Knight later confirmed there had been an issue with her set-up.
"We are obviously gutted with what happened," he said.
"Alice was incredible in warm-up this morning — good speed, good energy, dynamic skiing."
Fellow Kiwi Margaux Hackett is also out of medal contention in the women's freestyle skiing big air after failing to progress from yesterday’s qualifying.
Hackett crashed while attempting 900s on each of her first two jumps and, with the best two scores counting for each competitor, that meant her third and final jump was only for pride.
The 22-year-old did at least land that attempt, a switch right side 900, but finished 22nd of 25 athletes with a score of 74.75.
In the men’s big air freeskiing, Ben Barclay scored 162.75 to finish 16th and Finn Bilous 155.75 to finish 18th.
