Swiatek had said she needed a reset after her 75-week run as world number one came to an end.
"Unfortunately I need to withdraw from the tournament in Guadalajara due to a change of schedule," Swiatek posted on social media platform X.
French Open champion Swiatek, who was set to make her debut in the Sept. 17-23 Guadalajara tournament, said she would return to action in Tokyo at the start of next month.
U.S. Open champion Coco Gauff, defending Guadalajara champion Jessica Pegula, 2022 runner-up Maria Sakkari and Tunisia's Ons Jabeur have all entered the Mexico event.
